Calibration
Schweitzer Engineering Laboratories (SEL) performs a calibration of the
SEL-2032 clock at the factory. You do not need to periodically calibrate the
clock.
Battery Replacement
A battery maintains the clock (date and time) if the external DC source is lost
or removed. The battery is a 3 V lithium coin cell. At room temperature
(25°C), the battery will operate nominally for 10 years at rated load.
The battery experiences a low self-discharge rate when the SEL-2032 is
powered from an external source. If the source is lost or disconnected, the
battery discharges to keep the internal clock going. The battery cannot be
recharged.
CAUTION: There is danger of
explosion if the battery is
incorrectly replaced. Replace only
with Ray-O-Vac
®
no. BR2335 or
equivalent recommended by
manufacturer. Dispose of used
batteries according to the
manufacturer’s instructions.
Perform the battery replacement procedure if the SEL-2032 reports a battery
failure. You will also notice that the time and date are incorrect. To change the
battery, perform the following steps:
Step 1. Remove power from the SEL-2032.
Step 2. Remove any cables connected to Port F of the SEL-2032.
Step 3. Remove the front-panel screws and front panel.
