Install the Controller Chapter 2
To install an ESM, complete these steps. Follow the same steps for the safety
partner.
1. Align the tongue-and-groove slots of the ESM and controller.
2. Slide the ESM into the chassis until it snaps into place.
The ESM begins charging after installation. Charging status is indicated by one
of these status messages:
• ESM Charging
• CHRG
After you install the ESM, it may take up to 15 seconds for the charging status
messages to display.
ATTENTION: To avoid potential damage to the product when inserting the ESM,
align the ESM in the track and slide forward with minimal force until the ESM
snaps into place.
IMPORTANT Allow the ESM to finish charging before removing power from the controller. To
verify that the ESM is fully charged, check the status display to confirm that
messages ‘CHRG’ or ‘ESM Charging’ are no longer indicated.
TIP Check the WallClockTime object attributes after installing an ESM to verify that
time of the controller is correct.
