E-Stop Safety Modules with Adjustable Delay –
Models ES-TN-14H5/-14H6
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 E-Stop Safety 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
1-channel E-stop:
S21-S22
No monitoring:
X3-X4, X5-X6
Auto reset:
X1-X2
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, 33-34, 43-44, 57-
58, 67-68, 77-78, and 87-88 should close immediately, and contacts 91-92 and 01-
02 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, 23-24, 33-34, 43-44, 57-58, 67-68, 77-78, and 87-88
must open immediately; contacts 91-92 and 01-02 will close immediately. Contacts
57-58, 67-68, 77-78, and 87-88 open after the selected delay time; contact 01-02
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.
Figure 7. To remove the Module’s terminal
strips, insert a small screwdriver
blade into each of the four slots
at the top and bottom of the front
cover.
