6-2 Data Highway Cards
UM4.6:CS6003 Original — December 1991
6.1.2 Calibration Procedure
Use the following procedure to calibrate the card:
Step 1: Verify that the calibrator ON/OFF switch is OFF.
Step 2: Insert the power converter card shown in Figure 6-2, in the
test slot labeled MUX POWER CARD.
Step 3: Connect a jumper between test point TP1 and the common
(COM) test jack on the front of the of the power converter
card.
Step 4: Set the calibrator ON/OFF switch to ON.
Step 5: Disconnect the jumper and wait five minutes for the card
outputs to stabilize.
Step 6: Connect a voltmeter between test point TP1 and the common
(COM) test jack on the front of the power converter card. The
volt meter should read 3.69
± 0.015 volts dc. If not, adjust the
SUPV (R22) potentiometer to obtain the proper reading.
Step 7: Connect the voltmeter between the +5V and COM test jacks
on the front of the power converter card. The voltmeter should
read 4.855
± 0.002 volts dc. If not, adjust the +5 VOLT (R29)
potentiometer to obtain the proper reading. If unable to adjust
R29 for the proper reading, proceed to Step 17.
Step 8: Adjust the LOGIC RESET (R49) potentiometer on the power
converter card until the ON indicator on the power converter
card and the RESET TEST and RELAY TEST indicators of
the calibrator just go out.
Step 9: Adjust the +5 VOLT (R29) potentiometer on the power
converter card until the voltmeter reads at least 4.91 volts dc
and the ON indicator on the power converter card and RELAY
TEST and RESET TEST indicators on the calibrator light.
Step 10: Adjust the +5 VOLT (R29) potentiometer on the power
converter card until the ON indicator on the power converter
card and the RESET TEST and RELAY TEST indicators on
the calibrator just go out. The voltmeter should read 4.860
± 0.005 volts dc. If not, repeat Steps 6 thru 10 until the proper
reading is obtained.
Step 11: Adjust the +5 VOLT (R29) potentiometer until the voltmeter
reads 5.07
± 0.010 volts dc
Step 12: Connect the voltmeter between the +15V and COM test jacks
on the front of the power converter card. The voltmeter should
read between 14.05 and 14.60 volts dc and the ON indicator
on the front of the power converter card and the RELAY
TEST indicator go out. If not, adjust the +15 VOLT (R31)
potentiometer on the power converter card to obtain the
proper reading.
