Calibrating Regulator

16.Connect the 6.6 A series lighting circuit to the output terminals and tighten all connections.

NOTE: Do not route output cable in the vicinity of other wiring sensitive to EMI or RFI.

17.Check if the input current x input voltage x CCR efficiency (CCR efficiency = .90) is larger than the kilowatt rating on the CCR nameplate. If it is, either reduce the load or replace the CCR with one having a larger kilowatt rating.

18.Check current output on the regulator in all steps in both remote and local control.

NOTE: The regulator has been preset at the factory to the calibrated values given in ? If the regulator is not providing the correct current, it will have to be calibrated as given in Calibrating Regulator in this section.

This subsection describes how to calibrate the L-828 LC-type CCRs.

Introduction

Aseparate true-rms-reading ammeter (minimum accuracy of 1%, such as a Fluke Meter and Ammeter Probe multimeter with model Fluke Y8101A Current Probe current clamp or equivalent true RMS reading meter) is required to carry out the calibration of the regulator. Do not use the ammeter on the front panel of the regulator.

CAUTION: If the meter does not say “True RMS,” it must not be used. Failure to observe may result in equipment damage.

Calibrating the regulator consists of performing the procedures below in the order given.

1.Setting up the regulator

2.Adjusting output current

3.Adjusting overcurrent

4.Changing input voltage

5.Adjusting current sensing relay
