This brochure is organized into three main sections. They are: 1)
Sequence of Operation
, 2)
Installation
, 3)
Troubleshooting
. The
Sequence of Operation
section has three sub-sections. We recommend reading Section A:
General Operation
of the
Sequence of
Operation
, as this contains important information on the overall operation of the control. Then read the sub-sections that apply to your
installation.

POWERING UP THE CONTROL -----------------------------------------------------------------------------------------------------------------
-----------------------------------------------------------------------------------------------------------------
When the Pump Sequencer 132 is powered up, a software version code is displayed for 2 seconds, then the control turns on all
of the red LED’s for 2 seconds. After this test, the control enters its normal operating mode. When the control is powered up, the
Power
light remains on continuously.
OPERATION --------------------------------------------------------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------------------------------------------
The Pump Sequencer 132 has two modes of operation. The 132 is capable of operating two pumps in either a stand-by or 2-stage
configuration.
Stand-by
----------------------------------------------------------------------------------------------------------------
In the stand-by mode of operation the 132 automatically switches over from the lead pump to the stand-by pump if the lead pump
fails to provide flow in the system.
2-Stage
-----------------------------------------------------------------------------------------------------------------
In the 2-stage mode of operation the 132 turns on the second stage pump if there is a requirement for additional flow in the
system. At the same time the control still provides stand-by pump operation.
PUMP DEMAND --------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------
A pump demand is required in order for the 132 to provide flow. A pump demand is gener-
ated by applying a voltage between 24 and 240 V (ac) across the
Pump Demand
terminals
(1 and 2). Once voltage is applied, the
Pump Demand
light is turned on and the pump(s)
operate as required. A pump demand can be permanently powered, or generated from an
external source such as a manual switch or another control system.
