5 INSTRUMENTATION
Charger Fail Alarm LED indicator on front panel, Green = healthy / Red = failed.
Fault Alarm LED indicator on front panel, Green = healthy / Red = failed.
Volt free form C contact set, de-energising on fault. The charger failed
alarm must be active for 60 seconds to de-energise the fault signal.
6 CHARGING PROFILE
3 stage bulk / absorb / float modes. The charger will automatically switch to bulk (auto-boost) mode on
a low battery condition. Once the bulk voltage level is reached the charger will switch to absorb (boost
run-on) mode. The absorb time period is variable and dependent on the length of the bulk charging
period. On expiration the charger switches back to float mode.
7 COOLING
Convection cooled, bottom to top air-flow is required.

9 CONNECTION
NOTE:
Please refer to drawing on page 8
Do not expose the unit to rain or any form of moisture.
Avoid operation in direct sunlight and dust contaminated environments.
Ensure the units AC input supply is isolated.
Remove the terminal cover ensuring the cables are fed through the corresponding
apertures when making connections.
Ensure the AC input selector switch is in the correct position and connect the 110V or 230V
AC input supply.
Make necessary remote fault alarm and/or manual boost connections.
Connect the battery to the B-OUT (battery negative) and B+OUT (battery positive) terminals.
Always ensure the battery is of the correct type and number of cells.Note the alarm circuits
power-up when the battery is connected.
Switch on the AC input. After a short delay charge current will flow to the battery.
As the batteries charge the output current will reduce;
High output current = discharged battery, low output current = charged battery.
When the battery has fully charged its voltage can be checked with a DVM across the
battery terminals.
NOTE:
If the float voltage is adjusted from factory default then the alarm system MUST be
re-calibrated, following the instructions below.
10 APPENDIX A - Automatic Calibration Routine
NOTE:
The battery MUST be disconnected from the charger before proceeding.
Connect a DVM to the B+ / B- Out terminals of the charger. Set the float voltage to the desired
level by turning the 'Vfloat' multi-turn potentiometer.
Press and hold the ‘PROG’ push-button, all LED’s turn Red. Continue to hold for 10 seconds
until all LED’s turn Green then release the push-button.
Set the boost voltage to desired level by turning the 'Vboost' multi-turn potentiometer.
Operate and release the push-button again, the controller switches to float mode and all LED’s
are Red. Automatic calibration now commences.
After approximately 30 seconds the auto-calibration is complete and all LED's should be green
to indicate normal mode.

APPENDIX B - Manual Calibration Routine
When the automatic calibration levels are not suitable a manual calibration can be performed.
NOTE:
The battery MUST be disconnected from the charger before proceeding.
Power down the unit, hold the ‘PROG’ push-button down and power up the charger. Release
the 'PROG' push-button and the LED's will flash Red/Green in quick succession to indicate
manual calibration mode.
The following sequence must be followed by adjusting the float voltage potentiometer to the
desired voltage level at each stage:
Charger Fault Setting Procedure
Fail LED LED
Red Red Set Boost on Voltage, operate PROG push button.
Green Green Set Boost off Voltage (high level), operate PROG push button.
Red Green Set Boost off Reset Voltage (low level), operate PROG push button.
Red Red Set Charger Fail Low Voltage Alarm, operate PROG push button.
Green Red Set Charger Fail Low Voltage Reset, operate PROG push button.
Red Red Set Charger Fail High Voltage Alarm, operate PROG push button.
Green Red Set Charger Fail High Voltage Reset, operate PROG push button.
