GS-1AC Universal Generator StarterApplication

Used to control the starting and stopping of generators used as backup for battery systems. Generator starts if the battery voltage gets too low, and shuts off when the battery is near full.

Model: GS-1AC
Basic Operation

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 (GS-2AC) or open frame (GS-1AC) design for mount in your own enclosure.

Features

  • Single unit 12 V up to 48 V battery systems
  • LEDs indicate relay positions and generator status
  • 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

Electrical Specifications

  • Base Model: GS-1
  • Nominal battery voltages 12 - 48 V DC
  • Maximum Input (V) 63
  • Minimum Voltage 10
  • Relay: 8 amps @ 12/24 V , 2 amp @ 48 V , 5 amps @ 120 VAC rating of Potter and Brumfield T72 series relay
  • Self Consumption (A)
    • Relay Power: 0.5W per relay coil when powered, voltage independent
    • Quiescent less than 20 mA,Fusing 1 A, internal electronics only

Sequence of Operation on Startup

  1. When the battery voltage is detected as too low per user adjustable setpoint the generator goes through its start sequence.
  2. The Generator start LED comes on.
  3. Precrank: 20 seconds relay closure (with LED on) prior to generator start/crank.
  4. Crank: relay closure (with LED on) for 10 seconds or until Genset start detected defined by generator/battery voltage starting to rise.
  5. Run: Relay closure (with LED on) whenever generator is cranking or running.
  6. Load: load relay closure (with LED on) for 30 seconds after run relay closure.
  7. 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

  1. When the battery has charged to the user adjustable setpoint, the generator goes through its stop sequence.
  2. The Generator Stop LED comes on, start light turns off.
  3. Load: Load Relay opens (with LED off).
  4. Run: Run relay opens (with LED off) 20 seconds after load relay opens.
  5. 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

Special Shipping Note:
All Solar Converter Products are behind in production. These items are usually shipped directly from the manufacturer in Canada. They cannot be shipped by any expedited methods such as UPS Blue or Red. They will generally be shipped via Canadian Express Mail which avoids import brokerage fees of $50-$60. Lead time on these products may be up to 4-6 weeks depending on their production. This is true of all Solar Converters products with the exception of the battery desulphator (item code SORBD-2) that we stock in our warehouse. If you want Solar Converters products to be shipped by normal Canadian Post, but would prefer to have the rest of your order to be shipped by a faster method, please write this information in your order's notes during checkout.
