GPM-2 is a programmable motor protector, designed to control and monitor generators, motors,
compressors and motorised pumps, etc. It can be used with either 12 or 24V DC batteries.
1. OPERATION
GPM-2 has two operating modes, which can be selected by turning the switch to either MANUAL or AUTOMATIC.
Pressing the start button will send the corresponding command to the motor. Ignition will be deactivated when the “LOW
OIL PRESSURE” or “BATTERY CHARGE ALTERNATOR” pilot lights go off or the frequency exceeds 20 Hz.
When the switch is turned to “MAN”, the “LOW OIL PRESSURE” and “BATTERY CHARGE ALTERNATOR” pilot
lights will come on. If the start button has not been pressed after an interval of 60 seconds, the GPM-2 will stop the process
and activate a siren for 120 seconds.
When the switch is turned to “AUTO” and terminals 1 and 2 are both closed, the “LOW OIL PRESSURE” and
“BATTERY CHARGE ALTERNATOR” pilot lights will come on. Automatic operation is enabled and the corresponding
LED pilot light (AUTO TEST) is lit. The device will permit 3 ignition attempts. If the group does not start after the third
attempt, the “START UP FAILURE” alarm will be triggered. When terminals 1 and 2 are opened, the system times an off-
load running period and then commands the motor to stop. GPM-2 then disconnects from the battery and is available for a
new service.
2. SIGNALS
- AUTO TEST: Constant green/Remote operation
- PRE-IGNITION: Constant yellow/Pre-ignition
- STOP: Red
Flashing LED: Off-load running for 60 sec., after which GPM-2 stops the motor.
Constant LED: Stop command, 20 sec.
MAINTENANCE: Flashing yellow
1st maintenance: After 50 operating hours
2nd maintenance: 150 operating hours after the first maintenance (programmable)
RESET MAINTENANCE: Turn the switch to “STOP” and press during stop time.
3. ALARMS
- START UP FAILURE
Flashing LED: After three failed attempts, the siren is activated and the GPM-2 sends a stop command.
Constant LED: “Low voltage or frequency alarm”, the siren is activated. The GPM-2 sends a stop
command.
- BATTERY CHARGE FAILURE (BELTS BROKEN) (Timed: 20 sec.) BAT
Constant LED: Motor stopped (before start up), signal only.
Flashing LED: “Battery charge failure alarm”: the siren is activated and the GPM-2 sends a stop
command.
Constant LED: “Low water level alarm”: the siren is activated and the GPM-2 sends a stop command.
Flashing LED: “High water temp. alarm”: the siren is activated and the GPM-2 sends a stop command.
- OVERLOAD
Flashing LED: “Overload alarm”: the siren is activated and, after the programmed off-load running time,
the GPM-2 sends a stop command.
Flashing LED: “Emergency stop alarm”: the siren is activated and the GPM-2 sends a stop command.
Constant LED: “Excess speed alarm”: the siren is activated and the GPM-2 sends a stop command.
- OPTIONAL ALARM
