1 Phase Duplex
Operation, Maintenance and Installation Manual
Alarm Mode Configurations:
All "e" (economy) series control panels will only have a combination "test-normal-silence" switch where
automatic alarm reset is the only alarm configuration. When the panel goes into alarm, press the switch to
"silence" and the buzzer will turn off but the alarm indicator will remain on until the lag/alarm or alarm
level switch deactivates and automatically resets the alarm system.
All other Check It series control panels employ separate "test" and
"silence" switches. These panels can be field modified to have a "manual"
alarm reset. Refer to figure for placement of an 18 AWG jumper wire to
convert the panel from automatic reset to MANUAL reset. In the Manual
Reset mode and when the panel goes into alarm, the panel will remain in
alarm even if the alarm level switch is "opened" until the "silence" switch
is activated. This feature allows alarms to be manually acknowledged
before the alarm is cleared. In the event of a power failure, the alarm is
also cleared.
WARNING! When using the manual alarm reset feature you
must use a four float system. If you're using a 3 float system, add a fourth float and remove the yellow jumper
wire between the lag and alarm terminals to avoid dry pumping.
Use 18 AWG wire approximately 4" long. Strip off ¼" outer insulation. Insert jumper wire into the 2 posi-
tion wire port (one wire per port). To remove jumper wire, press small screw driver or pointed object onto
the "white" port block and remove wire as the wire is held in place by a spring cage terminal device.
Circuit Board Terminal Blocks:
The Check It series control panel uses two terminal blocks. A 10 position main terminal block is for power
and level switch connections. A separate 3 position terminal block are for dry auxiliary contacts. A 5 amp,
120 VAC max load can be applied to the auxiliary terminals. The auxiliary contacts are Form C, Single Pole,
Double Throw. (Common, Normally Open, Normally Closed). Contacts change state when in alarm condi-
tion.
