Introduction

The PumpSaver® ISS-105 IS Super Cell is a smart, five­channel, intrinsicall y safe relay and pump controller. It has a
long list of features that are needed for multiple pump
applications. The IS Super Cell can indicate low, high and out­of-sequence alarms. It can do alternating pump control, non­alternating pump control, or alternating control with one non­alternating pump. The non-alternating pump can be used as
either a jockey or emergency pump and can optionally start the
non-alternati ng pump after 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 IS Super Cell has the following features and capabilities:

4High, Low and Out-Of-Sequence Alarms
4Variable Time Delay/Lag Pump Delay
4Separate Pump Stop
4Pump Alternation w/ or w/o Non-Alternating Pump
4Jockey or Emergency Pump
4Duplex, Triplex or Quadplex Pump Modes
4Pump Up or Pump Down Functions
4External Silence, Reset and Alternation Configuration
4Five-Channel Relay

Quick Start

The IS Super Cell can operate as an intrinsically safe pump control 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 21 for the
full description of five-channel relay operation.

Read 1. Pumping Modes, page 6, for details of the features and mode
descriptions of the unit.

1. If the desired pump configuration is known, follow Table 1 to the
page showing the typical wi ring 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 pumpin g mode
and look at the typical wi ring diagrams of the eight different
pumping modes starting on page 11.

3. Once the desired configuration is determined, punch out and
slide the correct card i nto the slot on the front of the IS Super Cell
to display the input and output connections.

Model Description

WARNING!

The ISS-105 has three adjustable controls to set the mod e of operation:

1. Mode Selector

2. Option Selector

3. Time Delay

To ensure proper initialization and operation,
set the m ode and option selectors before applying
power to the unit.

Time Delay

The Time Delay can be set from 2–255 seconds and is the Lag Pump
delay in each of th e pumping modes. When the Lead Float
opens/closes, the Time Delay starts and once i t expires, the Lag Pump
is ready to turn on. After the Lag Pump turns on, any necessary pumps
will turn on suc cessively after a two-second time delay each.

Mode Selector

This dial is used to select the operation mode. A description of each
mode is shown i n Table 1. The capabilities of each pumping mode and
the Non-Alternating Pump designations are shown in Table 2 below.

1. Pumping Modes

Duplex

In a Duplex mode, two pumps are used with one Stop Float and High
and Low Alarms.

Triplex: High/Low Alarm

In a Triplex mode, three pumps are used with one Stop Float.
In a Triplex Pump Down mode, a High Alarm is the typical

configuration with the Option Selector switches 1=ON (High Alarm) and
2=OFF (Low Alarm).

If a Low Alarm is desired, the al arm float must be moved to the position
in the tank below the Stop Float and Option Selector switches must be
1=OFF and 2=ON.

In a Triplex Pump Up mode, a Low Al arm is the ty pical configuration
with the Option Sel ector switches 1=OFF (Hi gh Alarm) and 2=ON (Low
Alarm).

If a High Al arm is desired, the alarm float must be m oved to the position
in the tank above the Stop Float and Option Selector switches must be
1=ON and 2=OFF

Quadplex

In a Quadplex m ode, four pumps are used with one Stop Float and no
alarms floats.

Separate Pump Stop (SPS)

In the Duplex SPS mode, both the Lead and Lag pumps have their own
stop floats.

In an SPS Pump Down mode, a High Al arm is th e typical configuration with
Option Selector switches 1=ON (High Alarm) and 2=OFF (Low Alarm).

If a Low Alarm is desired, the alarm float must be moved to the positi on
in the tank below the Lead Stop Float, and Option Selector switches
must be 1=OFF, and 2=ON.

In an SPS Pump Up mode, a Low Alarm is the typical configuration with
Option Selector switc hes 1=OFF (High Alarm) and 2=ON (Low Alarm).

If a High Alarm is desired, the alarm float must be moved to the
position in the ta nk above the Lead Stop Float, and Option Sel ector
switches must be 1=ON and 2=OFF.

2. IS Super Cell Functions

High Alarm

The High Alarm is activated when the High Alarm Float closes,
indicating the pumps are unable to keep the water level down on a
Pump Down applic ation. If the High Al arm Float closes at any time, all
pumps will turn on, bypassing th e 10-second out-of-sequence trip delay,
and the adjus table Time Delay.

If a High Alarm is used on a Pump Up application, the alarm will be
activated when the High Alarm Float cl oses 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 flas h indicating the alarm had occu rred,
but is not present now. If the High or Low Alarm occurs again, the
Audible Alarm LED will turn on again, but t he Alarm LED will rem ain
flashing.
The unit must be silenced or reset to clear the flashing al arm LEDs.

Low Alarm

The Low Alarm 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 Al arm is activated, all pumps will turn on.

If a Low A larm is used on a Pump Down application, the alarm will be
activated when the Low Alarm Float opens indicati ng 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 required.

Out-of-Sequence Alarm

When a float i n the series does not open or close in sequence, the
Audible Alarm will be activated and input LED(s) will flash until t he unit

7

12/04

is reset or power is cycled. An out-of- sequence condition has to exist for
10 seconds before th e ISS-105 will alarm. W hen the stop float fai l s open
in pump down mo de 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 is activated. Thus, in
Quadplex mode, pumps will never turn on if th e Stop Float ma lfuncti ons.

Audible Alarm

The Audible Alarm is activated when a High, Low or Out-of Sequence
Alarm occurs. The Audible Al arm 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 rela y can be configured to operate in either a Fail­Safe mode (p osition 7=ON), or a Non Fail-Saf e mode (position 7=OFF).
In Fail-Safe mode, the NC (Normally Closed) contacts will beopen
during normal operation and closed during an alarm. In Non Fail-Safe
mode, the NC contacts will be cl osed during normal operation and open
during an alarm.

Clearing Alarms

The external Silence / Alarm Reset button will clear t he Audible Alarm.
The Reset button or cycling power will clear Out-of-Sequence Alarms.

Alternation

The ISS-105 i s equipped with a built-in alternator that determines which
pump will st art each pum ping cycle. This alt ernator is configured using
switches ALS-0, ALS-1 and ALS-2 of the Option Selector.
