8.6.1 Replacing the battery in a hazardous DIV-1/ZONE-0 environment
A special operating mode is provided to allow changing of a battery pack in a hazardous location. (If the
location is known to be non-hazardous, for example, if the location has been tested for the presence of
gas and it has been determined that gas is not present, this section can be skipped. Go to the Replacing
the battery in a non-hazardous environment section). The special operating mode puts the corrector in a
standby condition in which volume continues to be accumulated and event logging and alarms are still
active, but all other functions are stopped to ensure very low power drain. This allows a low power (Swap
out) battery (40-6054) to be plugged in while the main battery pack (40-6048) is changed, and then
removed after the new battery back is plugged in.
To replace the battery in a hazardous DIV-1/ZONE-0 environment, perform the following steps:
l
Enter HMI and set the EC350 to Battery Change mode. You can use the L2.11 or L3.13 HMI menus.
l
The BATT CHNG message is displayed on the LCD screen. Press the Enter key.
l
Select Yes and press Enter. The unit is now ready for a battery change out. CHNG BATT THEN ESC
is displayed on the LCD screen.
l
Plug the Low Power (Swap out) Battery (part no. 40-6054) into the open connector on the battery Y
cable.
l
Unplug the old battery.
l
Plug in the fresh battery (part no. 40-6048) where the old battery was plugged in.
l
Remove the Low Power (Swap out) Battery
l
Press the ESCkey twice to exit the battery change mode. When the ESC key is pressed, all the
battery life items are automatically set to 100% new values and the battery usage cycle is set to
zero.
