Note:
1. If the override facility is used and the battery voltage drops below 11.0V the contactor may not disconnect the load. When power is applied to the override pin there may be a delay of up to 30 seconds before the contactor switches.
2. Varies with switch on voltage setting

An override pin allows the load to be connected1 for emergency use only.
To reduce power consumption to a minimum (10mA “On”, < 1mA “Off”) a latching contactor is used.
When the contactor is “On” the coil is pulsed to ensure it remains on
When the contactor is “Off” the coil is pulsed for approx. 2 minute before the unit goes to low power mode.
The Switch “On” and Switch “Off” voltages are factory set but can be adjusted by the customer.
There are 2 light emitting diode (led) indicators:
Red “ON” is used as a multipurpose indicator:

There are 2 light emitting diode (led) indicators:
Red “ON” is used as a multipurpose indicator:
1. Led on – load is connected (there could be a delay after the led lights before the load is connected)
2. Led off - the unit is in low power mode
3. Led flashes each time the contactor coil is pulsed
4. Aids setting of the switch “On” and “Off” voltages
White “LOW BATTERY” lights for 2 minutes before the battery is disconnected
