Page 34: Maintenance
Inspect the relay for obvious signs of damage or ingress of moisture or other contamination. Terminal Base Isolate the relay; remove the retention screws & un-plug the 1S20 module from the terminal base. Care must be taken to avoid subjecting the relay element to static discharge which may damage or degrade sensitive electronic components. - Page 35 >20,000 Lux and 2ms is recommended. STEP TWO Connect up the 1S20, 1S30 with a dropping resistor & storage CRO as per the test diagram. Activate the 1S30 sensor using a camera flash gun positioned directly in front of the sensor window and check that the 1S30 trip LED activates.
- Page 36 STEP THREE The test described in step two is used to prove the operating performance of the 1S20 Arc Fault Monitor. To check the performance of the complete system the 1S30 performance must also be checked. Make up an Arc Detection Interface Unit (ADI) and connect up to the 1S20, 1S30 with a dropping resistor &...
