Periodic Checkout Procedure
The functioning of the E-stop system must be verified periodically to ensure proper
operation (see also the machine manufacturer’s recommendations).
NOTE: If two or more E-stop switches are series-connected to one E-stop Safety
Module, this test must be individually run for EACH switch.
Procedure:
1. With the machine running, engage the E-stop switch (open its contact). Verify that
the machine stops.
2. Return the E-stop switch to its closed-contact position. Verify that the machine
does not restart.
3. Close and then open the Reset switch (if using manual reset mode). Verify that the
machine restarts.

CAUTION . . .
Disconnect Power Prior
to Checkout
Before performing the
initial checkout procedure, make
certain all power is disconnected
from the machine to be controlled.
Dangerous voltages may be present
along the E-Stop Safety Module
wiring barriers whenever power to
the machine control elements is ON.
Exercise extreme caution whenever
machine control power is or may be
present. Always disconnect power to
the machine control elements before
opening the enclosure housing of the
E-Stop Safety Module.
E-Stop Safety Modules ES-TN-1H5 and -1H6 provide seven indicator LEDs
Power
(green)
ON – Power is connected to terminals A1-A2
OFF – No power or low power to terminals A1-A2, or internal power supply failure
Fault
(red)
ON – External fault or configuration fault. The corresponding function LED (see below) will flash to indicate the area where the
fault has been detected. See Fault Indication Table for probable cause.
Flashing – Internal Fault. See page 16 for repair.
E-Stop
(green)
ON – E-Stop inputs are closed (S11-S12 and S21-S22).
OFF – E-Stop inputs are open.
Flashing (Fault LED OFF) – If the Module is configured for Manual Power-up and Auto Reset, the E-Stop button must be cycled
(opened, then closed) to enter RUN mode. (Ensure Cancel Delay input is open or a fault will occur.)
Flashing (Fault LED ON) – See Fault Indication Table for probable cause.
Reset
(green)
ON – Reset input is closed (X1-X2).
OFF – Reset input is open.
Flashing (Fault LED OFF) – “Reset Requested.” The Reset input (button) must be cycled (closed, then opened), to enter
RUN mode.
Flashing (Fault LED ON) – See Fault Indication Table for probable cause.
Monitor
(green)
ON – Monitoring inputs are closed (X3-X4 and X5-X6).
OFF – Monitoring inputs are open.
Flashing (Fault LED ON) – See Fault Indication Table for probable cause.
Out
(green)
ON – Both internal relays K1 and K2 are energized. (Immediate N.O. outputs 13-14 and 23-24 are closed. Immediate N.C. output
51-52 is open.)
OFF – Both internal relays K1 and K2 are de-energized. (Immediate N.O. outputs 13-14 and 23-24 are open. Immediate N.C.
output 51-52 is closed.)
Timed-out
(green)
ON – Both internal relays K3 and K4 are energized. (Delayed N.O. outputs 37-38 and 47-48 are closed. Delayed N.C. output
61-62 is open.)
OFF – Both internal relays K3 and K4 are de-energized. (Delayed N.O. outputs 37-38 and 47-48 are open. Delayed N.C. output
61-62 is closed.)
Flashing (Fault LED ON) – See Fault Indication Table for probable cause.
