2000 ECS-12U Controller J85501E-2
5 - 2 Acceptance Testing Issue 3 July 1998
NOTE Unless otherwise indicated in the test procedures, at least one
rectifier must be on line in batteryless plants.
Meter Calibration The controller voltmeter has an accuracy of 0.05% and a
resolution of 1 digit. To verify the calibration of the voltmeter,
an external meter with better than 0.05% accuracy is needed. If
such a meter is not available, only a rough assessment of the
controller meter calibration can be achieved. The controller
meter is factory calibrated and should not be adjusted in the field
unless it is obviously outside the tolerance of the external meter.
If calibration is needed, set the meter select switch to the VOLTS
position. Adjust Potentiometer R407 on CP4, which is part of the
113B control unit. (See Figure 2-3 for its location.)
Battery on
Discharge Alarm
Test
NOTE The Battery on Discharge Alarm test procedure is to be
performed without an office load.
If the test must be performed on a live plant (with office
load), first notify the alarm center, then shut off rectifiers
one at a time. Observe the BD alarm, then restore all
rectifiers to normal as quickly as possible.
1. Identify the BD threshold level set on DIP switch SW103.
2. Set the controller meter select switch to the VOLTS
position and verify that the plant voltage is above the BD
threshold.
3. Turn off all but one rectifier until rectifier capacity is less
than plant load.
4. Adjust the test load to draw 5%-10% of the rectifier rating.
5. Adjust the rectifier output voltage down until the BD LED
on the controller lights. This should occur at the set
threshold within the tolerance specified in Table 2-B.
If Step 5 fails to produce the desired result, more load may
be required if a large capacity battery string is connected.
