Test The Power Supply -----------------------------------------
Make sure exposed wires and bare terminals are not in contact with
other wires or grounded surfaces. Turn on the power and measure the
voltage between the Power N and Power L terminals (11 and 12) using
an AC voltmeter. The reading should be between 108 and 132 V (ac).
Test The Powered Inputs ---------------------------------------
Pump Demand
Measure the voltage between the Pump Demand terminals (1 and 2).
When the pump demand device calls for flow, you should measure
between 20 and 260 V (ac) at the terminals. When the pump demand
device is off, you should measure less than 5 V (ac).
2-Stage Demand
If a 2-stage demand is used, measure the voltage between the
2-Stage Demand terminals (3 and 4). When the 2-stage demand
device calls for flow, you should measure between 20 and 260 V
(ac) at the terminals. When the 2-stage demand device is off, you
should measure less than 5 V (ac).
Flow Proof
Measure the voltage between the Flow Proof terminals (5 and 6).
When the flow proof device is energized, you should measure
between 20 and 260 V (ac) at the terminals. When the flow proof
device is off, you should measure less than 5 V (ac).
Test The Outputs ----------------------------------------------------------------
Pump 1 and Pump 2
Make sure power to the terminal block is off and install a jumper between Pump 1
terminals (7 and 8). When the pump circuit is powered up, the pump should start. If the
pump does not turn on, check the wiring between terminal block and pump and refer
to any installation or troubleshooting information supplied with the pump. If the pump
operates properly, disconnect the power and remove the jumper. Repeat the above
procedure for Pump 2 terminals (9 and 10).
Alert A and Alert B
If an alert is connected to the Alert A terminals (13 and 14), make sure power to the alert circuit is off and install a jumper
between the terminals. When the alert circuit is powered up, the alert should turn on. If the alert does not turn on, check the
wiring between the terminal block and alert and refer to any installation or troubleshooting information supplied with the alert.
If the alert operates properly, disconnect the power and remove the jumper. If an alert is connected to the Alert B terminals (15
and 16), repeat the above procedure for Alert B.
