Ver especificaciones Ocultar
Un controlador de arranque / apagado y funcionamiento completamente desatendido para equipos impulsados por motor. Este controlador basado en microprocesador, fácil de usar, compacto y de última generación, cubre todas las operaciones básicas de arranque y parada además de otras características que solo se encuentran en controladores más sofisticados y costosos.
El A91 está diseñado para funcionar con una batería de 12 o 24 voltios y requiere un sensor magnético (captador) para la detección de velocidad.
- Power Input: 12 or 24 VDC nominal (specify).
- Standby Power Consumption: <50mA.
- Magnetic Pickup Input: Requires 2 V rms minimum.
- Sensor Input Polarity: Negative (-).
- Outputs: Five (5) open collector transistor 500 mA sink. Two (2) relay, 5 Amp maximum at 12 or 24 VDC (sourcing).
- Reverse Polarity Protection: 200 volt peak reverse voltage.
- On-board Memory: 8k PROM (programmable, read only memory); data retention 10 years.
- Operating Temperature Range: -20 to 140°F (-25 to 60°C).
- Operating Humidity Range: 0-95% Non-Condensing
- User Trip point Adjustments: Five (5) on-board potentiometers (320° turn).
- Test-Off-Automatic Toggle Switch: Three position switch for:
- Test: Starts engine in automatic mode and runs until switched “off” or emergency shutdown occurs.
- Off: Disconnects all power to control circuits, Stop/disables engine from starting and resets shutdown indicators.
- Auto: Automatic start/stop sequencing is initiated by external switches and signals.
- Cycle Crank Timer: 5 crank attempts 7 seconds each; 4 rest periods 15 seconds each, before overcrank.
- Overspeed Trip Point Setting: From 2500-9000 Hz.
- Crank Disconnect Speed Setting: From 400-2500 Hz.
- Shutdown Time Delay: 15 seconds after engine start; locks out low lube oil and high temperature.
- Engine Run LED: Turns“on”when crank disconnect occurs.
- Shutdown Output: Removes DC output or operates dry relay contacts for engine shutdown (depending on model used).
- Start/Stop: SPDT momentary; or SPST maintained switches.
- Warmup Time Delay: Field adjustable from 0-300 seconds to load the engine after warmup (model -WC only).
- Cooldown Time Delay: Field adjustable from 0-300 seconds (model -WC only).
- Enclosure: Weatherproof NEMA 3R.
- Enclosure Coating: Red enamel.
- Subpanel Coating: White enamel.
