INTRODUCTION
The PumpControl
™
Model PC-105 is a five-
channel pump controller that can handle
multiple pump applications or operate as a
5-channel switch. The PC-105 can indicate
low, high and out-of-sequence alarms and
use alternating pump control, non-
alternating pump control, or alternating
control with one non-alternating pump. The
non-alternating pump can be used as either
a jockey or emergency pump and can
optionally be cycled once every 50 cycles of
the lead pump to keep it working freely.
Using the built-in DIP switches, individual
pumps can be disabled when taken out of
service for repair or maintenance.
The PC-105 has the following features and capabilities:
4
High, low and out-of-sequence alarms
4
Variable time delay/lag pump delay
4
Separate pump stop

QUICK START
The PC-105 can operate as a pump controller for eight different pumping configurations. Duplex,
triplex, quadplex and duplex SPS (separate pump stop) pumping modes are possible for either
pump-up or pump-down applications. Refer to page 18 for the full description of five-channel relay
operation.
Refer to
PUMPING MODES
(page 4) for details of PC-105 features and mode descriptions.
1. If you know the system’s pump configuration, follow Table 1 to the page showing the typical
wiring diagram and setup for each mode.
2. If further description is needed in choosing which mode to use, see Table 2 and Table 3 to view
the capabilities of each pumping mode and look at the typical wiring diagrams of the eight
different pumping modes starting on page 8.
3. Once the desired configuration is determined, punch out and slide the correct card into the slot
on the front of the PC-105 to display the input and output connections.

Time Delay
The time delay can be set from 2–255 seconds and is the delay before the lag pump will turn on in
each of the pumping modes. When the lead float closes (direct logic), the time delay starts and
when it expires, the lag pump is ready to turn on or will turn on if the lag input is closed (direct
logic). All subsequent pumps will turn on as called for after a two-second time delay each.
Mode Selector
The mode selector switch sets the operation mode. A description of each mode is shown in Table
1. The capabilities of each pumping mode and the non-alternating pump designations are shown in
Table 2 below.

PUMPING MODES
Duplex
– two pumps with one stop float, a high alarm and a low alarm.
Triplex: High/Low Alarm
–
three pumps with one stop float and a high or low alarm.
Triplex Pump-Down
: a high alarm is typically used—Option Selector: 1=ON, 2=OFF.
If a low alarm is preferred, the alarm float must be moved to the location in the tank below the
Stop Float—Option Selector: 1=OFF and 2=ON.
Triplex Pump-Up
: a low alarm is typically used—Option Selector: 1=OFF, 2=ON.
If a high alarm is preferred, the alarm float must be moved to the location in the tank above the
Stop Float—Option Selector: 1=ON and 2=OFF.
Quadplex
– four pumps with one stop float and no alarms floats.
Separate Pump Stop (SPS)
– two pumps, two stop floats, and a high or low alarm.
In
Duplex SPS
mode, both the lead and lag pumps have their own stop floats.
Duplex SPS Pump-Down
: a high alarm is typically used—Option Selector: 1=ON, 2=OFF.
If a low alarm is preferred, the alarm float must be moved to the location in the tank below the
Lead Stop Float—Option Selector: 1=OFF, 2=ON.
Duplex SPS Pump-Up
: a low alarm is typically used—Option Selector: 1=OFF, 2=ON.
If a high alarm is preferred, the alarm float must be moved to the location in the tank above the
Lead Stop Float—Option Selector: 1=ON, 2=OFF.
PC-105 FUNCTIONS
High Alarm
The High Alarm relay is activated when the High Alarm Float closes, indicating the pumps are
unable to keep the water level down on a pump-down application. If the High Alarm Float closes at
any time, all pumps will turn on, bypassing the 10-second out-of-sequence trip delay, and the
adjustable Time Delay.
If a high alarm is used on a pump-up application, the alarm will be activated when the High Alarm
Float closes indicating the water level has been pumped too high, possibly due to a defective Stop
Float, and will turn off all pumps.
During a high or low alarm, the Alarm LED and Audible Alarm LED will be on. If the high or low
alarm condition ends, the Audible Alarm will turn off and the Alarm LED will flash indicating the
alarm had occurred, but is not present now. If the high or low alarm occurs again, the Audible
Alarm LED will turn on again, but the Alarm LED will remain flashing. The unit must be silenced or
reset to clear the flashing alarm LEDs.
Low Alarm
The Low Alarm relay is activated when the Low Alarm Float opens indicating the pumps are unable
to keep the water level up on a pump-up application. If the pump-up Low Alarm Float opens at any
time, except if a High Alarm is activated, all pumps will turn on.
If a low alarm is used on a pump-down application, the alarm will be activated when the Low Alarm
Float opens indicating the water level has been pumped too low. This may be a result of a defective
stop float. The low alarm will not turn off the pumps though, but will activate the low alarm relay—
another form of pump-dry protection such as the SymCom Model 777 may be necessary.
Littelfuse_ProtectionRelays_001925__II_PC_105_B-html.html
5
10/06
Out-of-Sequence Alarm
When a float in the series does not open or close in sequence, the Audible Alarm relay will be
activated and input LED(s) will flash until the unit is reset or power is cycled. An out-of-sequence
condition has to exist for 10 seconds before the PC-105 will alarm. When the stop float fails open in
pump-down mode or closed in pump-up mode, an out-of-sequence alarm will not occur and pumps
will not turn on with floats. In this case, all pumps will turn on when the High/Low Alarm input is
activated. Thus, in Quadplex mode, pumps will never turn on if the Stop Float malfunctions.
Audible Alarm
The Audible Alarm relay is activated when a high, low or out-of-sequence alarm occurs. The
Audible Alarm will turn off when there is no longer high or low alarms or if the unit is silenced.
Audible Alarm Logic / Fail-Safe
The Audible Alarm relay can be configured to operate in either fail-safe mode (switch 7=ON), or
non fail-safe mode (switch 7=OFF). In fail-safe mode, the N.C. (normally closed) contacts will be
open during normal operation and closed during an alarm. In non-fail-safe mode, the N.C. contacts
will be closed during normal operation and open during an alarm.
Clearing Alarms
The external Silence / Alarm Reset button will clear the Audible Alarm. The Reset button or cycling
power will clear out-of-sequence alarms.
Alternation
The PC-105 is equipped with a built-in alternator that determines which pump will start each
pumping cycle. This alternator is configured using switches ALS-0, ALS-1 and ALS-2 (switches 8, 9
and 10 of the Option Selector).

Note (3) In Duplex Mode, Pump 2 is the Lead Pump and Pump 1 will be cycled every 50 cycles of the Lead.
* If ALS-0 is ON in this mode, the Non-Alternating Pump will cycle when the non-alternating float changes state,
or after 50 cycles of the Lead float.
** If ALS-0 is OFF the Non-Alternating Pump will cycle only when the non-alternating float changes state.

Table 5. Pump Sequence
Alternation On, Non-Alternating Pump Enabled
The Triplex and Quadplex pump modes are equipped with an optional Non-Alternating Pump. This
pump will
not
be included in the normal pump alternation sequence when ALS-1 and ALS-2
(switches 9 and 10) are both OFF. If ALS-0 (switch 8) is ON, the non-alternating pump will cycle
when the Non-Alternating Float changes state or after every 50 cycles of the Lead Float. If ALS-0 is
OFF, the non-alternating pump will only cycle if the non-alternating float changes state.
The last pump in the float sequence (highest #) is the non-alternating pump and can be used as
either a jockey or emergency pump. (See Table 2, page 3 for non-alternating pump and float details
for each pumping mode.)
A
Jockey Pump
is typically a smaller pump that will always be used first in the pump sequence.
In order to implement a jockey pump, the non-alternating pump float must be moved in the tank
to just above the Stop Float on a pump-down system, and to just below the Stop Float on a
pump-up system. See
Figure 9 (page 16)—an example wiring diagram using a jockey pump in a duplex pump-down
system.
An
Emergency Pump
is usually a larger pump that is always used last. In order to implement an
emergency pump, the non-alternating pump is already the last pump in the sequence so there is
no need to move the float. See Figure 10 (page 17)—an example wiring diagram using an
emergency pump on a duplex pump-down system.
Alternation Off
When the alternator is off, a Lead Pump can be forced by setting ALS-0, ALS-1 and ALS- 2 (see
Table 4). The remaining pumps will start in a sequential order as each float opens/closes.
Disabling Pumps
Using the built-in DIP switches, individual pumps can be disabled, when taken out of service for
repair or maintenance.

External Inputs
A five-pin connector is provided for optional external inputs.
· External Silence / Alarm Reset
This input allows for an external N.O. (normally open) pushbutton that will silence audible
alarms and clear flashing alarm lights.
· External Power Reset
This input allows for an external N.O. pushbutton to reset the PC-105, causing the same effect
as a power cycle.
· External Alternation Configuration
For duplex mode, a SPDT (single-pole, double-throw) switch can be connected to close RTCL1
or RTCL2 (remote controls) to force Pump 1 or 2 as the Lead Pump. Option Selector switches
8, 9 & 10 must be OFF. If the switch is in the middle position, pumps will be in alternation mode.
For triplex and quadplex modes, two SPST (single-pole, single-throw) switches can be
connected to force Pump 1, 2, 3 or 4 to be the Lead Pump. Option Selector switches 9 & 10
must be OFF.
To force Pump 1 or 2 as Lead, Option Selector switch 8 must be OFF.
To force Pump 3 or 4 as Lead, Option Selector switch 8 must be ON.
For alternation mode, close both RTCL1 and RTCL2.

Table 16: Five-Channel Relay Options
Positive/Negative Logic
Using
positive logic
will give the same output as input—if the input is closed, the corresponding
output relay is closed.
If using
negative logic
, the output will be the opposite of the input—if the input is closed, the output
relay is open.
Latched Output
Relays 2 and 4 can be configured as latched relays. Input 2 will cause relay 2 to close, but this
relay will not open until input 1 opens. Relay 4 will close when input 4 closes, but will not open until
input 3 opens.
Time Delay Output
Relay 5 can be configured as a Delay-On-Make or a Delay-On-Break time delay output. All timing
starts when the input switch opens or closes. The time base for this output is adjustable using the
Time Delay knob and ranges from 2-255 seconds.
Delay-On-Make
If Input 5 closes, the Time Delay will start and LED 5 will flash. Once the time delay has
expired, output relay 5 will close and the LED will be on. If Input 5 opens at any point during the
timing cycle, the time delay stops and output relay 5 remains open.
Delay-On-Break
If input 5 opens, the time delay will start and LED 5 will flash. Once the time delay has expired,
output relay 5 will open and the LED will be off. If input 5 closes at any point during the timing
cycle, the time delay stops and output relay 5 remains closed.
