ACCEPTANCE TESTS 

4. ACCEPTANCE  TESTS 

Acceptance tests include tests for both HID module and the latching relay 86. 

For the latching relay, this manual proposes to test the open and close coils operation, and the correct contact 
activation. 

4.1 

WIRING AND NECESSARY EQUIPMENT 

Necessary equipment: 

1 AC voltage source. 

1 DC voltage power supply. 

1 timer. 

1 Multi-meter. 

External wiring diagram: B5180F* 

NOTE: Groups described in the tests correspond to an HID model with three inputs. For other models, please 
check the corresponding external wiring diagram.  

 

 

4.2 

VISUAL INSPECTION 

 

Verify that the HID unit has not suffered any damage due to its handling and transport. 

 

Verify that all the screws are correctly fixed and that the terminal board is in good condition. 

 

Check that the information shown on the relay identification label corresponds to the requested relay model. 

 

 

4.3 

CONTINUITY 

Test equipment: 

An Multimeter or continuity measurer with a maximum threshold of 110 

Ω

. 

 

Method: 

Check for continuity between the grounded screw and any metallic point of the case that has no painting on it.
