L-828 CCRs LC-Type (4, 7.5, and 10 kW/6.6 A/60 Hz)

Installation

Setting Up Regulator for Calibration

To set up the regulator for calibration, perform the following procedure:

1.See Figure 2-4. Check to make sure the proper input voltage is supplied to the CCR at terminal block TB3 (12).

2.Make sure the transformer output connections are at the 100% tap (terminals 1 and 6).

3.See Figure 3-1. On the output terminals, connect a true rms- reading ammeter, such as a Bechman Tech 360 multimeter, and a lamp load equal to one-half of the CCR’s rated load. If the load is greater than one-half of the CCR’s rated load, short output varistors RV2 (10) to RV3 (9).

4.See Figure 2-4. Set CCR’s local control switch S1 (6) to the highest intensity step (S1 position fully clockwise), 5 for 5-step CCR or 100 for a 3-step CCR.

5.See Figure 3-1. Turn the overcurrent-adjustment potentiometer R48 (8) on the control PCB fully counterclockwise.

6.See Figure 2-4. Turn on the CCR. Observe normal operation for a minimum of 2 minutes during which time the output should not vary and only the green LED marked REGULATOR ON (5) should be lit. No red alarm LEDs should be lit.

Adjusting Output Current

To adjust the output current, perform the following procedure:

1.See Figure 2-4. Turn on the CCR and set local control switch

S1 (6) to the highest intensity step, 5 for 5-step CCR or 100 for a 3-step CCR.

NOTE: See Figure 3-1. The external true-rms ammeter (1) should read 6.60 ±0.1 amps. If the reading is outside of this range, adjust potentiometer R47 (7) on the Control PCB to obtain 6.60 amps.

NOTE: Potentiometer R47 is the master reference adjustment. Changing this potentiometer changes the adjustment of potentiometers R48 (8), R46 (6), R45 (5), R44 (4), and R43 (3).
