Maintenance
Dry Contact Relay
Digital Meter - Option V
This charger requires no maintenance other than the occasional wipe down to remove dust
that could reduce its ability to dissipate heat. Carefully blow air through the cooling vent to
remove any dust buildup inside the unit.
The charger can be fitted with a 1 amp dry contact relay to indicate charger status to a moni-
toring system. It has both a normally-open and normally-closed contact which changes state
depending on the presence or absence of charging voltage on the output and is independent
of the microprocessor.
If the charger is producing voltage on the output, the normally closed contact will be closed
and there will be an electrical connection between NC and COM. If the voltage on the output
of the charger goes to zero, the contact will change state. The Normally Open contact oper-
ates exactly in the reverse of the Normally Closed contact.
The BCDi320 can be equipped (by factory order) with a bright chassis-integrated digital meter
to display the battery voltage and charging current being supplied to up to both connected
batteries. This digital meter option adds 2.5-3 inches to the length of the chassis.
