The Model ISS-105 IS Super Cell is a “smart” five-channel intrinsically safe relay and
pump controller. It can operate in a wide variety of pumping configurations including
alternating or non-alternating duplex, duplex separate pump stop (SPS), triplex and
quadplex for either pump up or pump down applications. It can also be set up as a
simple five channel intrinsically safe relay.

The IS Super Cell has a long list of “smart”features that are needed for multiple pump
applications. The IS Super Cell can indicate low, high and out-of-sequence alarms.
If an out-of-sequence alarm occurs, the skipped pump(s) will be star ted as intended.
The Model ISS-105 can be set up to do non-alternating control, alternating control and
alternating control with one non-alternating pump.The non-alternating pump is intended for
use as an emergency pump or jockey pump. The IS Super Cell can start the non-alternating
pump once every 50 cycles 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.
ISS-105 must be installed in a non-hazardous area.Follow SymCom’s Control Drawing 105
for proper installation (See ISS-105 installation guide).
