e. Remove the Test Jumper and press the Reset PushButton PB1 on the decoder to clear the fault.
f. Apply power to the controller (set to ‘ON’). OPR1, OPR2 and the programmed main relays (M1-M6)
should energize.
From your customized system interface drawings, determine a motor direction relay output to be
tested (for example, ‘BF’ in Figure 16). This output will have a corresponding ASO input (for example,
‘ASO-BF’). Install a Test Jumper across the terminals of this motor direction relay output. Notice that
the corresponding ASO input relay energizes and then ASO Stage 1 occurs – the main output relay
(‘MAIN 1’) for that motor is disabled, together with the matrix relay outputs (‘Bridge Directions and
Speeds’) for that motor.
The decoder system status display posts a bulletin indicating the input was energized without
command, together with the outputs that have been disabled. Note that the other motor outputs
and their auxiliary output functions are still operational.
g. Remove the Test Jumper and touch one end to the ‘hot’ terminal of the main output relay for that
motor (in this example, the ‘odd’ numbered terminal of MAIN 1), as shown in Figure 16.
h. Touch the other end of the Test Jumper to the ‘energize’ terminal of the corresponding ASO input (in
this example, the ‘even’ numbered terminal of ‘ASO BF’). The ASO input relay will energize and
Stage 2 shutdown occurs – OPR1, OPR2, all main and all function outputs will be disabled.
The system status display will post a ‘system shutdown’ bulletin because the function was energized
without a command.
i. Remove the Test Jumper and press the Reset PushButton PB1 on the decoder to clear the fault.
j. Repeat steps i. thru l. above for each of the remaining motor directional relay outputs identified on
your customized system interface drawings.
If any relay fails the ASO test, replace the relay in accordance with the instructions in the
Maintenance section of this manual and repeat the test. If the relay fails again, the decoder board is
suspect and may need replacing.
k. After testing all relays, remove the Test Jumper and close the cover of the receiver/decoder.
l. Before restoring power to the crane or machine motors, completely isolate the controller by
setting the system STOP switch to ‘STOP’ and the ON/OFF switch to ‘OFF’.
m. Return the crane or machine motor control switches to the ON position.
n. Check each controller function carefully. Observe the system for proper operation of all functions.
o. Check for proper range of control by operating the various machine functions while moving around in
the system’s operating area. Move to the extreme edges of the operating area and ensure that the
system functions still operate properly. Control should be maintained at all times. Check any optional
receiver features like Close Start or Range Limit (refer to Appendix I – R2HN Receiver for details).
If all the above steps have been successfully completed, your PRC system is now fully operational.
