E-Stop Safety Modules with Fixed Delay –
Initial Checkout and Troubleshooting Procedure
NOTE: If more than one E-Stop switch is series-connected to one E-Stop Safety
Module, this checkout procedure must be run individually for each switch.
1. Remove power from the machine being guarded and from the Module.
2. Activate the E-stop buttons (open their contacts).
3. Remove the E-Stop Safety Module front cover, (see Figure 5).
4. Check for correct settings on the DIP switches S1-S4 and S1.1-S4.1 (see
Figure 6). The related pairs of switches (S1/S1.1, S2/S2.1, S3/S3.1, and S4/S4.1)
must match at all times, as must the two Delay Time selector switches (T1/T2).
5. After switches are set to the proper position for the application, replace the E-Stop
Safety Module front cover.
6. Make sure that jumpers, if required, are installed:
1-channel monitoring: X5-X6
No monitoring:
7. Turn the power ON to the E-Stop Safety Module. All LEDs will turn ON for a period
of about 0.5 seconds, after which time all but the power LED will turn OFF for
about 0.5 seconds; then the normal status indicator function will be displayed.
If any LEDs do not cycle ON, then OFF after power is ON, disconnect power and
check all wiring; return to step 5 after correcting the problem. If the problem
cannot be corrected, return the Module to the factory for repair (see step 12 and
page 16).
8. E-Stop LED will be OFF if the E-stop contacts are not closed. Out and Timed-Out
LEDs must be OFF; Monitor LED must be ON (monitor inputs are closed). The
Reset LED must be OFF if configured for Manual Reset, and ON if configured for
Automatic Reset.
9. Arm the E-stop button.
If the Module is set for Auto Reset, output contacts 13-14, 23-24, 37-38, and
47-48 should close immediately, and contacts 51-52 and 61-62 should open
immediately. E-Stop, Out, and Timed-Out LEDs must all come ON.
If the Module is set for Manual Reset, the E-Stop LED will come ON.
After the E-Stop button is armed and the Reset LED starts flashing, reset the
Module by closing and opening the reset input. (The Reset button should remain
closed longer than 100 ms, but not longer than 2.5 seconds. The Reset LED will
begin to flash again if the button is held in too long.) After Reset is opened, the
Out and Timed-Out LEDs must come ON immediately. All normally open output
contacts are closed now, and all normally closed output contacts are open. The
Reset LED will be steady ON as long as the reset input is closed; it will go OFF if
the reset input is opened and the four relays are ON.
10. Activate the E-Stop switch (open its contacts); the E-Stop LED must go OFF. Out
LED must go OFF. Contacts 13-14 and 23-24 must open immediately; contact 51-
52 will close immediately. Contacts 37-38 and 47-48 open after the selected delay
time; contact 61-62 closes after the selected delay time. Timed-Out LED will go
OFF after the delay time is over.
11. (Optional) Close the Cancel Delay input to immediately terminate the delay.
12. If the complete Safety Module must be replaced, the modular terminal strips
may easily be removed for quick installation into another module. To remove the
terminal strips, first replace the Safety Module front cover. Then insert the blade
of a small screwdriver into one of the four depressions in the Safety Module front
cover and pry them loose; see Figure 7.
