Ensure the connections to the relay coil are the correct way round ! Failure to ensure this will result in
the relay having exactly the opposite action to that required. The terminal marked “REL –“ on the
PCB should be connected to the unmarked coil contact on the relay. The terminal marked “REL+” on
the PCB should be connected to the coil contact marked with a “+” on the relay.
WARNING
Incorrect connections to any of the terminals may cause permanent damage to the unit which
will not be covered under warranty.
Installation and usage notes
SmartGuard will not allow the reset button to attempt to
close
the relay unless it was actually SmartGuard
that
opened
it in the first place. For this reason it may be found that, following installation or trouble
shooting (for instance if the relay was installed or supplied in the latched open position) the relay is latched
in the open position and therefore the entire electrical system is shut down. It would seem that there is no
way out of this situation without disconnecting the relay and manually connecting it to the batteries
temporarily to reset it. This is not the case. Simply press the reset switch and HOLD it pressed. After
approximately 6 seconds the LED in the switch will start to blink. Releasing the switch whilst the LED is
blinking will force the relay into the latched closed position.
