(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. Configurations The ESCR rectifier is available in the following configurations: ESCR-20/10-12/24V-AV1 This model can be configured for 12V-10AMP or12V-20AMP or 24V-10AMP...
2.1.3 Start-Up Sequence Upon powering up the ESCR the LCD will display the model number. During the start up sequence, the Low DC voltage alarm will be temporarily activated.
– The Charger Fail LED will illuminate when the charger is not able to regulate the output voltage. The LED will stay lit, even after the alarm conditions clear up, until the ESCR unit is reset. A set of Form C contacts is also provided to enable the customer to connect a remote annunciator.
Each of the adjustable settings of the ESCR is accessible using Configure mode. Once in Configure mode the user can navigate using the Up and Down arrows to the right of the display, the Reset/Back button and the Configure/OK button.

Service All work inside the ESCR should be performed by a qualified electrician. La Marche is not responsible for any damages caused by an unqualified technician. Before working inside the ESCR ensure that the AC Power is off at the main breaker box. Disconnect the battery from the charger via the battery disconnect breaker or manually disconnecting the battery cables.
Troubleshooting Procedure Troubleshooting should be performed only by trained service personnel or experienced electricians. Before setting up any complicated testing, give the unit a general inspection. Check the following: 1. Check DC output cables, connections, battery type, and number of cells against the unit’s rating. 2.
