GENERATOR START CONTROL MODULE - MINI (2 Wire to 3 Wire)
GSCM-mini-D WITH A MANUAL/OFF/AUTO SWITCH OPTIONS
The Manual start signal is created by connecting terminal 5 (man. Start) to terminal 3 (B+12VDC) through a Power/Reset Switch (see
GSCM-mini-D wiring diagram). It may also be generated by an Outback Inverter using the AUX+/- connections on the remote terminal
block. The Outback provides a switched +12VDC signal for the GSCM-mini-D's manual start input. An optional Manual-Off-Auto switch
can be installed to provide user flexibility for manual starts, resets, turning the unit off, or Auto starting from Inverter.
(see GSCM-mini-D's wiring diagram, lower right hand corner).
GSCM-mini-D FAULT SHUTDOWN CONDITIONS
The GSCM-mini-D detects Five (5) fault shutdown conditions, they are as follows:
1.
Failure to start with 3 cranking attempts (see Section-1:3, 2:2, & 3:3 ). The Gen. Hz Shutdown LED does a double blink and Fault
LED On continuously.
2.
High frequency (over Hz.) condition. The generator AC frequency is monitored on terminals 9 and 10. If the Gen. Hz. enable
terminal #8 is grounded and the generator output frequency exceeds the 65 Hz fixed threshold for 10 seconds, the generator shuts
down and the Generator Hz shutdown LED blinks rapidly. The "Generator Hz" LED blinks during this 10 second period.
3.
Low frequency (under Hz.) condition. If the Gen. Hz. enable terminal #8 is grounded and the generator output frequency remains
below the 55 Hz fixed threshold for 10 seconds, the generator shuts down and the Generator Hz shutdown fault LED blinks slowly.
The "Generator Hz" LED blinks during this 10 second period.
4.
Auto Start within 30 minutes of Max Run Time shutdown (see Section-6:4 ). The Gen. Hz Shutdown LED does a triple blink and
Fault LED On continuously.
5.
The GSCM-mini-D is in run mode, and the generator shuts down on a fault condition (low oil pressure, Hi temperature, or out of
fuel) or the AC Hz signal fuse or wire opens or the 12v run status wire opens, the GSCM-mini-D goes thru it's shutdown routine
and enters a fault condition, turning on the red Fault LED and blinking the Gen Hz LED four times every two seconds.
The over/under Hz. detection not enabled until the generator has been running for 60 seconds and will shutdown the generator after 10
continuous seconds of Hz. fault condition, locking it out until a power down reset and power back up. The Fault open collector transistor
output (terminal 12) will energize a user supplied remote lamp or DC relay (not exceeding 300 milliamp coil current) whenever a fault
shutdown occurs and will de-energize the relay when the fault is reset.
AUTOMATIC STARTING FOR BATTERY CHARGING
The GSCM-mini-D can monitor either the generator battery voltage or a battery bank voltage and Automatically start/stop the generator
based on battery voltage. This is accomplished by connecting the battery voltage to the battery sense input (terminal 4). The GSCM-
mini-D monitors a battery voltage range of 0 to 60V DC and automatically determines the start and stop set point based on battery
voltage (12, 24, or 48VDC). Below 16VDC - uses 12V thresholds, between 16 to 32V -uses 24V thresholds, above 32V - uses 48V
thresholds. This mode is disabled if the voltage on terminal 4 is less than 6V, (no connection).
1.
The GSCM-mini-D monitors the battery sense input and when the battery voltage drops below the start threshold the Start LED
begins blinking (every second). When the battery voltage has remained below the start threshold for 5 continuous minutes the Auto
start sequence begins. If the battery voltage rises above the start threshold during the 5 minute period the 5 minute timing cycle
starts over. (Temporary battery voltage fluctuations such as instantaneous inverter loads will not start the GSCM.) The start LED
blinks every 3 seconds while the GSCM-mini-D is running the generator in auto-start mode.
2.
The GSCM-mini-D starts the generator as described in sections 1: momentary start, 2: maintained start, or 3: ignition start.
3.
The GSCM-mini-D shuts down the generator (as described in Sections 1, 2, or 3) whenever the battery voltage exceeds the stop
threshold for 10 minutes. The Start LED blinks (every second) during this 10 minute period. The GSCM-mini-d will exit the 10
minute period and shutdown the generator if the battery voltage exceeds the stop point by +1.0V (for a 12V system, 2V for 24V
system). The generator remains off until the battery voltage drops below the start threshold voltage.
4.
The GSCM-mini-D will shutdown the generator when it has run in auto-start battery charging mode for 6 hours and has not charge
the battery above the shutdown threshold. The GSCM-mini-D then returns to ready mode looking for a start command. If the battery
voltage drops below the Auto start threshold within 30 minutes of a max Run Time shut down the GSCM-mini-D will enter a Max
run time fault condition and lock out the start sequence and requires a power down reset. The Gen Hz LED will blink 3 quick blinks
every 5 seconds and the fault LED is on continuously.
5.
If the user wishes to manual-start the generator from a separate pressure switch, level switch, thermostat or inverter start contact,
etc., the battery voltage is fed through the switch (pressure switch etc.) contact to Manual start terminal 5. Closing the contact will
cause the GSCM-mini-D to start the generator. Some invertors provide a switch 12VDC signal to start the generator. This switched
voltage can be connected directly to the manual start terminal 5 and ground terminal 7. (See GSCM-mini-D wiring diagram).
