E-Stop Safety Module –

SECTION 6 — Troubleshooting

Use the indicator LEDs on the E-Stop Safety Module to diagnose fault type (see Section

5.3). Use your DeviceNet Manager as a troubleshooting aid. Also, see the most current

Electronic Data Sheet (EDS) file; it assigns a number to a specific text string that will be

helpful in troubleshooting problems.

The ES-TA-3F1 E-Stop Safety Module also features a self-contained provision for

troubleshooting; indicator LEDs on the front cover provide clues to possible faults. If the

circuit is working properly, the Power LED should be ON, and the individual indicator

lights for each Emergency Stop switch input should remain ON.

If one of the Emergency Stop switches connected to the circuit has been activated, its

indicator on the front panel of the module will go OFF; in addition, each indicator to the

right of it on the panel will also go OFF. (For example, if switch #4 has been activated, the

indicators for switches 4, 5, 6, 7, 8, 9 and 10 will be OFF.)

To reset, begin by verifying that the problem prompting the E-stop procedure has been

corrected. The E-stop switch indicator, and all those to the right of it on the control

module front panel, should go ON. Then activate the Reset switch connected to the

E-Stop Safety Module, and reset the E-stop switch indicated by the first LED to be OFF,

reading from left to right on the control panel. (For example, if switch #4 has been

activated, the indicators for switches 4, 5, 6, 7, 8, 9 and 10 will be OFF; start by resetting

switch #4.) Verify that all monitor indicators are ON. (If one of the monitor inputs is

open, its indicator will go OFF; in addition, each monitor indicator to the right of it will

also go OFF. For example, if monitor 2 is open, the indicators for monitor 2, 3 and 4 will

be OFF.)

If any of the E-stop switch indicators remain OFF, repeat this step with the next E-stop

switch indicator (again, the first/left-most unlit LED on the front of the module

control panel).

NOTE: After a successful reset, both of the K1/K2 indicators should be ON. If not, the E-Stop

Module has an internal fault and should be returned to the factory for repair.
