2 GENERAL TESTS
2.1 Status Inputs
This test checks that the status input circuits are functioning correctly. The status input circuits should be
energised in turn and observed to be operating using the instruments mode 'Status Inputs' display. A '1' indicates
that the status circuit is energised, a '0' indicates that it is not.
Where practical operate the initiate condition of the status input, or failing this, connect the relevant D.C. voltage
to the status input terminals to energise them:

Note: Status operating voltage need not be the same as the main energising voltage. For 110/125 volt or 220 /250
volt working, a standard status input, 48/54 volt rated will be supplied with external dropper resistor as follows:-
