This Genset starter monitors the
battery voltage, and when the battery voltage gets too its low setpoint,
the unit starts the generator. When the battery gets to its high setpoint,
the unit stops the generator. The generator may be remotely started and stopped
by dry contact closures, or by its local toggle switch start stop commands.
The setpoints may be temperature compensated with an optional remote temperature
sensor.
Available in Model (GS-1AC) optimized for starting AC generators. This
product is available in an enclosure or open frame design for mount in your
own enclosure.
Features
- Single unit 12 V up to 48 V battery systems

- Temperature compensation (-4 mv / deg C./ cell) on start and stop voltages
with optional temperature sensor TC-2
- remote start and stop controls as well as local start/stop control
- 5 second retirggerable time delay on voltage sensing to prevent false
starts/stops
- Supports 2, 3 and 4 wire systems as well as advanced control systems
- Low Cost/ High Reliability

Sequence of Operation on Startup
When the battery voltage is detected as too low per user adjustable setpoint
the generator goes through its start sequence.
- The Generator start LED comes on.
- Precrank: 20 seconds relay closure (with LED on) prior to generator
start/crank.
- Crank: relay closure (with LED on) for 10 seconds or until Genset start
detected defined by generator/battery voltage starting to rise.
- Run: Relay closure (with LED on) whenever generator is cranking or
running.
- Load: load relay closure (with LED on) for 30 seconds after run relay
closure.
- If battery voltage falls another 0.2 V (relative to 12 V battery),
fault relay is activated for remote signaling of fault.
Sequence of Operation on Shutdown
When the battery has charged to the user adjustable setpoint, the generator
goes through its stop sequence.
- The Generator Stop LED comes on, start light turns off.
- Load: Load Relay opens (with LED off).
- Run: Run relay opens (with LED off) 20 seconds after load relay opens.
- Stop: Stop relay Closes (with LED on) for 10 seconds after run relay
opens.
User Controls
- Generator Stop Voltage
- Generator Start Voltage
- Manual start/stop toggle switch overrides remote smart stop control
- Remote start/stop
- Potentiometers and test points read 1/10 the voltage you wish to start/stop
the generator. For example, if the generator is required to start at 23 V,
set the start potentiometer for 2.3 V
LED Display
- Generator start/stop
- Relay position for precrank, crank, load, run, stop, fault
