Automation DC Power • Powering the Network
I) Time Buffering/Battery Run Time Settings:
dial in time
interval of desired run time of battery without disconnect.
a. 1 - 60 minutes
or
b. Set at zero for battery run until LVD activates
@ 18 VDC (1.5 VPC)

for details.
J) Battery Start w/o AC Present Push Button:
a. If system shuts down due to loss of AC and battery,
power push button will allow battery to reconnect and
supply the load if sufficient battery voltage is present.
K) Status Indicator LED’s
1. AC Fail: Operating on battery back-up power (LED
On). LED extinguishes when AC is present.
2. Low battery, or poor battery condition
3. Charger Output Status and Fault Mode Diagnosis: by
blink code:
Charge Status Blink Code:
• Bulk: 5 blink/second - Recovery
• Absorption: 2 blink/second - Bulk
• Float: 1 blink/second
Fault Mode Diagnosis Blink Code:
• Reverse Polarity: 1 blink, pause
• Battery Not Connected: 2 blink, pause
• Overload or Short Circuit: 4 blink, pause
• Bad Battery Wire Connection, or Bad Battery
(internal impedance): 5 blink, pause
• Bad Thermal Sensor: 7 blink, pause and diagnostic

outputs 29.2 VDC for two
minutes, then output is
reduced to 28.8 VDC
*NiCad Battery Charge Parameters
Caution!
When configuring for NiCad use, the Battery Charging Level adjustment on front panel must be set to at least 30%
of the capacity of the battery being charged (ie at least 30% of battery rated Amp-Hour capacity), (Note, the adjustment
range of Battery Charging Level dial on the unit is 4 amps minimum, 20 amps maximum.)
If set below the prescribed 30% minimum Ah capacity, the control circuit may not be able to sense battery absorption
rate, and thus not terminate absorption charge cycle until 16 hours has passed, potentially resulting in battery over-
charge.
Float Charge: Constant current, rate =10% of the set Battery Charging Level
Absorption Charge: 31.0 VDC (1.55 VPC x 20 cells).
Termination of absorption charge is determined by an automatic battery test applied after entering absortion mode:
• If test indicates battery will not maintain its voltage (ie drops by > 0.1 volts) absorption mode will continue for a
maximum 16 hours before reverting to float mode.
• If test indicates battery voltage is maintained (i.e. drops <0.1 volts), absorption mode times out after 10 minutes,
and reverts to float mode.
