Functional Verification (Proof) Test Procedure (module level):
This procedure requires a digital multi-meter for resistance and voltage measurement. This will require
password access to the front panel menus.
1. Cycle Power on the module and verify there are no internal faults on the Alarm Latch page of the
monitor menu.
2. Remove power from one power supply input (power supply input 1 or 2) at a time and verify the
correct fault is read on the Alarm Latch page of the monitor menu.
3. Measure external 24 V EXT (terminals 80—81; 23 ±1 V).
4. Measure SPEED PWR (terminals 69—71). Insure active probe mode is selected in Speed
Configuration Menu, make the measurement, and insure probe type is in original configuration (23
±1 V).
5. Test Speed input by using one of the internal speed test modes in the Test Menu. Resistance
measurement of each of the voter outputs is required. Verify as follows:
a. With module not tripped, resistance measurement from 1A—1B, or
2A—2B must be less than 100
.
b. With module tripped, resistance measurement from 1A—1B, or
2A—2B must be greater than 1 M
.
6. Cycle dedicated inputs and verify the proper signal by monitoring the respective input on the Monitor
Menu/Dedicated Discrete Input page of the front panel.
7. If possible, compare external speed with measured speed-reading on the ProTech-GII display.
8. If used as part of the safety system, verify the analog output. Measure this output by performing an
automated overspeed trip test as described in
step 6.
9. Chassis isolation checks using resistance measurement. Measure from terminals 66, 67 to a point
on the ProTech-GII chassis (the grounding braid is a good place for this measurement): < 1
.
10. Perform a lamp test from front panel Test Menu.
