Cleaning
If dust or metal filings are present inside the unit, clean with vacuum or compressed air. Otherwise, no cleaning
inside the unit is required. Optionally, if the cover becomes dirty, you can wipe it with a damp cloth and mild
detergent.
Required Battery Maintenance
Battery life expectancy is a function of its discharge cycles (the number of discharges and their depth) and the
ambient temperature of the battery during normal operation. In most applications, the battery should see
relatively few discharges. Therefore, ambient temperature has more to do with determining the life expectancy
of the battery than does any other factor. If the JO-PC1 is installed in a conditioned space, the battery should
provide dependable service for approximately three years (average). In an environment where the operating
temperature is higher (that is, 50ºC or 122ºF), you should only expect the battery to last approximately one year.
The NiMH battery in the JO-PC1 controller is fully discharged when factory shipped. Additionally, NiMH
batteries lose charge over time if not kept trickle-charged (for more details, see
page 18).
Therefore, even a new unit (or replacement battery) will require up to 18 hours of powered operation before it
can provide reliable backup power (is at full charge).
The controller monitors the battery and periodically loads the battery to test its ability to maintain battery-backed
functions. Investigate any battery trouble message, and check the battery connections to the unit. Replace the
battery as required. To order a new battery, see the
Replacing the Battery
The replacement JENE-PC-BPPM battery is a complete assembly, that is a custom NiMH battery pack
pre-attached to a battery bracket. See
Caution
Use only battery packs approved for use with the JO-PC1 controller.
To replace the battery, proceed as follows:
Procedure 7
Replacing NiMH battery assembly on a JO-PC1.
Step 1
Backup
the
controller’s
configuration
to
your
PC
using
the
appropriate
NiagaraAX
software
tool
(for
example,
Workbench).
Step 2
Remove power from the controller.
Wait for LED activity to stop—after several seconds, all LEDs on the JENEsysONE should be off.
Step 3
Remove the cover. See
