Initial Checkout Procedure
Checkout procedure:
1) Remove power from the machine control elements.
2) Activate the E-stop switch (open its contact).
3) Apply power to one side of the E-stop switch. No indicator should be ON at this
time. If any of the three indicators is ON, disconnect the power to the E-stop
switch, then check all wiring and the E-stop switch. Return to step 2 after the
cause of the problem has been corrected.
4) Arm the E-stop switch (close its contact). The Power LED must come ON.
5) NOTE: If configured for automatic reset, K1 and K2 indicators should come ON,
and the safety output contacts should close.
If configured for manual reset, close the Reset switch. The K1 and K2 indicators
should come ON. Open the Reset switch. The K1 and K2 indicators should both
stay ON. If none or only one of the two K1 and K2 indicators comes ON, check the
wiring. If the wiring is OK, the unit has an internal fault.
6) Activate the E-stop switch (open its contact). The K1 and K2 indicators should turn
OFF simultaneously. If either indicator is not OFF, disconnect the input power and
check all wiring. Return to step 2 after the cause of the problem has been corrected.
7) Close the enclosure. Apply power to the Machine Control Elements and perform
the Periodic Checkout Procedure (see below).
NOTE: If more than one E-stop switch is series-connected to one E-stop Safety
Module, the above checkout procedure must be run individually for
EACH switch.
Periodic Checkout Procedure
The functioning of the E-stop system must be verified on a regular periodic basis to
ensure proper operation (see also the machine manufacturer’s recommendations).
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 start.
3) Close and then open the Reset switch (if using manual reset mode). Verify that the
machine restarts.
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.
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.
