5 Start-up Operation
Only trained technicians should perform the following:
•
Check mounting location.
•
Check power voltage.
•
Check for correct sensor element (7 MSR) at sensorboard terminal X3 PCB EC-C.
•
Check and/or select the appropriate jumpers for remote alarm function, relay R3 (see section 5.5,
motherboard jumper selection table).
•
Check and/or select the appropriate jumper for failure function, relay R2 (see section 5.5, motherboard
jumper selection table).
•
Check and/or select the appropriate jumper for latched function, relay R2 (see section 5.5, motherboard
jumper selection table).
•
Check and/or adjust trip/setpoints for low and high alarm levels (see section 5.1, motherboard
potentiometers R31and R32).
•
Check and/or put switch into “Auto” position, manual override of low alarm.
•
Verify sensor/transmitter operation by mearsuring approximately 200 mV (about 0 ppm CO) on
sensorboard terminal -X6 and +X6.
Required instruments to start-up and calibrate the SPC:
•
Test gas bottle with synthetic air.
•
Test gas bottle with 200 ppm CO.
•
Gas pressure regulator with flow meter to control the gas flow at 300 ml/min.
•
Sensor head calibration adapter with tubing.
•
Digital voltmeter with a range of 0-2 VAC and 0-10 VDC, accuracy 1%
•
Small screwdriver.
Note:
Please observe proper handling procedures for test gas bottles!
5.1 Set trip/setpoints
5.1.1 Set low and high trip/setpoints without optional digital display
Set low trip/setpoint
•
Connect a digital voltmeter to test jacks J1 (red) and JM (black) on the motherboard with a range selected
that will display 10 VDC maximum.
•
Adjust the low trip/setpoint voltage, with potentiometer ”R31” at the motherboard, until the signal reads the
appropriate mVDC ± 2 mV (see section 5.1.2, calculation for trip/setpoint control voltage).
Set high trip/setpoint
•
Connect a digital voltmeter to test jacks J2 (red) and JM (black) on the motherboard with a range selected
that will display 10 VDC maximum.
•
Adjust the high trip/setpoint with potentiometer ”R32” at the motherboard until the signal reads the
appropriate mVDC ± 2 mV (see section 5.1.2, calculation for trip/setpoint control voltage).
