With the probe connected, enter the Configuration Mode and make
sure that Temperature Compensation has been enabled (For more
details, see section 2.3).

Operation
2.1
Starting the ESCR125
All equipment is shipped from the factory fully checked and adjusted based on the factory settings
listed below. Before connecting the battery, check with the battery manufacturer for the correct voltage
settings and adjust the configuration accordingly (refer to section 2.3 for configuration). Failure to
match the charger settings with the connected battery may damage or shorten the life of the battery.
Factory Settings
The factory settings of the ESCR125 are based on the customer order, unless otherwise specified. All chargers
are set at the factory with the following default settings.
Battery Type:
60 (Cell Lead Acid)
Float Voltage:
2.17 Volts/Cell (V/C) for Lead Acid (LA)
1.44 V/C for Nickel Cadmium (NC)
Equalize Voltage:
2.33 V/C for LA (1.55 V/C for NC)
Current Limit:
105%
Equalize Hours:
8 Hours
Equalize Mode:
Manual
Temp. Compensation:
Disabled
High DC Voltage:
2.45 V/C for LA (1.6 V/C for NC)
Low DC Voltage:
1.98 V/C for LA (1.2 V/C for NC)
Alarm Delay:
5 Seconds
2.1.1 Checking the Installation
Before starting up the ESCR125, check and verify that all connections are correct. Check that all terminations
and contacts are tightened securely. Check that the transformer is set for the correct input voltage. Check that
the input frequency matches the nameplate of the charger. Check that the battery voltage matches the DC
output voltage on the nameplate of the charger.
2.1.2 Starting/Stopping the ESCR125
Once proper connections are established, energize the charger by turning on the charger’s AC breaker (the DC
breaker should be off). This will charge the capacitors inside the charger and eliminate heavy arcing when the
batteries are connected. After about 30 seconds, turn on the DC breaker. When shutting down the ESCR125,
switch off the DC breaker first and then switch off the AC breaker.
2.1.3 Start-Up Sequence
Upon powering up the ESCR125, the LCD will display “La Marche ESCR”. During the start up sequence, the Low
DC Voltage alarm will be temporarily activated. The display will show “Float Mode” and the output Voltage and
Current of the Charger will slowly ramp up. After reaching the output voltage, the Low DC Voltage alarm will
deactivate.
