6.2.2Sensor/Electronics Functionality Verification

1.Turn power off to Innova-Switch™.

2.Allow a 5 minute cool down.

3.Measure the resistance of each RTD at pins 1 and 6 of TBA (see Figure 6.0 or 7.0) for the hot RTD and pins 3 and 5 of TBA for the cold RTD. These resistances should be 110 ± 10 ohms (with sensors at approximately 70°F) and within 5% of each other in value.

4.Measure the insulation resistance between pin 1 of TBA and the case of the Innova-Switch™. It should greater than 20 megohms.

5.If the Innova-Switch™sensor assembly resistances are not as specified above, the switch sensor assembly must be replaced.

6.If the Innova-Switch™sensor assembly resistances are as specified, the Innova- Switch™ PC electronic board must be replaced.

SPECIAL NOTICE

The electronic assemblies contained in the Innova-Switch™ are configured for specific voltages and have specific modifications to accommodate the various agency approvals. When ordering spare electronics, replacements, or exchanges in the field please ensure you identify the specific configuration you have by noting the boxes marked on the transformer configuration tag.
