4.4.5 Alarm Contacts Connections
4.4.5.1 On Battery Alarm
Terminal block accepts #18 to #24 AWG wire and provides three terminals (Form C contacts) which
are NO, COM and NC. The relay is energized whenever at least one battery is connected to a load.
4.4.5.2 Over Voltage Protection Alarm
Terminal block accepts #18 to #24 AWG wire and provides three terminals (Form C contacts) which
are NO, COM and NC. The relay is energized whenever an OVP (over voltage protection) condition
has occurred and the charger was unable to recover. Note: The OVP relay will be deenergized dur-
ing a low voltage disconnect even if an OVP condition exists.
4.4.5.3 Charger Fail Alarm
Terminal block accepts #18 to #24 AWG wire and provides three terminals (Form C contacts) which
are NO, COM and NC.
The Charger Fail relay is normally energized and will deenergize when
charger fail condition occurs. The charger will indicate a failed condition if it is unable to source
power. Possible fail conditions are AC fail, OVP trip, V
OUT
< 9 V, fuse fail, on battery (transfer ),
unable to source current into the battery.
The charger incorporates a “voltage ramp” to determine if it is able to source current into the bat-
tery. Whenever the output current to the battery drops below 5 % of the rated output, the charger
will intermittently (about once per minute) increase the voltage. This should cause the output cur-
rent to increase above the 5 % level. As soon as the current rises above 5 %, the ramp will be ter-
minated. If no increase in the output current is detected, the charger fail alarm will be activated.
4.4.6 Temperature Compensation Probe Installation
Terminal block TB4 accepts #18 to #24 AWG wire and provides 3 terminals. `COM' is the common
for the temperature probes (black wire). `1' and `2' are the positive terminal connections for the
temperature probes (red wire).
When one probe is used, terminals '1' and '2' are jumpered together. If the jumper is not installed
the charger will read a discrepancy between probe terminal 1 and 2. See the section 'Temperature
Compensation' for details.
If a second, redundant probe is to be used, the jumper must be removed and the positive (red)
wires from the probes are individually inserted in the terminals marked 1 and 2 and the negative
(black) wires are both inserted into the terminal marked COM.
Generally the temperature probe(s) should be mounted on the battery in the warmest location.
When 2 separate battery strings are used in a system and the batteries are not located in the same
area the probe(s) should be connected to the battery string which is expected to be the warmest.
The temperature probe(s) can be strapped to the center of one side of the battery with an adhesive
tape. If 2 probes are used they should be spaced apart approximately 1" (2.5 cm). When multiple
batteries are used in the system the probe should be placed between the batteries so heating from
the other batteries will be detected by the probes.
