plant
The 216A ECS Thermal Compensation Unit described in
Section 2 can be retrofitted into a J85500D-x battery plant. The
kit (Comcode 847618105) contains the circuit packs, wiring and
hardware to monitor one string of batteries.Read the instructions
below before beginning, observe all the safety warnings and
notes, and follow the instructions step by step.
WARNING:
Procedures in this section may cause power alarms to be
issued temporarily. Notify the alarm reporting center before
starting any replacement procedure to an operating plant.
Tools required
•
5/16” Nutdriver
•
7/16” Nutdriver
•
Jeweler’s Screwdriver
•
Wire Strippers (22 AWG)
•
Heat Gun
1. Mount the VR Module bracket to any one of the available
1/4 - 20 Pem-nuts in the battery stand upright. Then attach
the Terminal Block Assembly Base to the VR Module
bracket with the 10-32 screws provided. (See Figure 4-9.)
2. Temporarily insert the thermistors in the battery locations
to be monitored. See Figure 4-8 for suggested locations
between the Lucent Technologies VR Batteries. Dress the
thermistor wire sets from the Terminal Block Assembly to
the thermistors and cut to proper length. The thermistors
will need to be removed from the battery string during
testing so do not secure them into place at this time.
3. Connect all thermistor wire sets (maximum = 8 per 216A)
to terminal blocks TB101 & TB102 as shown in Figure 4-
10. The ambient temperature of the thermistor must be
between 0°C (32°F) and 53°C (127.4°F) when the wire
set is connected to the Terminal Block Assembly in order
for the proper temperature to be sensed by the 216A
Control Unit.
4. Mate the 216A Control Unit to the Terminal Block Base
Assembly, See Figure 4-9. Latch the two units together
with the clips on the base.
