Checkout Procedures

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 Safety Module wiring barriers whenever power to the ma-
chine 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 enclo-
sure housing of the Safety Module.

At installation or replacement and at machine set up, a Designated Person

must test each input device connected to the safety module

for proper machine shutdown response. A Designated Person must check for proper operation, physical damage, mounting (looseness),
and excessive environmental contamination. This must also take place on a periodic schedule determined by the user, based on the
severity of the operating environment and the frequency of switching. Adjust, clean, repair, or replace components as needed when any
parts or assemblies are damaged, broken, deformed, or badly worn; or if the electrical/mechanical specifications (for the environment and
operating conditions) have been exceeded. Always test the control system for proper functioning under machine control conditions
after performing maintenance, replacing the safety module, or replacing any component(s) of the safety circuit.

Initial Checkout

1. Remove power from the machine control elements.
2. Ensure the safety device is in a STOP or "open-contact" state (for example, actuate the E-stop switch to open its contacts).
3. Apply power to the Safety Module at terminals A1 and A2 (see the hookup configurations in

Safety Input Device Hookup Options

page 5). Verify that only the Input Power indicator is ON (

Figure 1. Features

on page 3). If either input channel 1 (K1) or input channel

2 (K2) indicators are ON at this point, disconnect the input power and check all wiring. Return to step 2 after the cause of the problem
has been corrected.

4. Reset or otherwise cause the safety device to reach an ON or "closed-contact" state (for example, arm the E-stop switch to close its

contacts).

5. Reset the safety module.

Automatic: Ch1 (K1) and Ch2 (K2) indicators should come ON, and the safety output contacts should close as soon as the input

device(s) are ON.

Manual:

From an open condition, close the reset switch for approximately ¼ second, and then re-open. The Ch1 (K1) and Ch2
(K2) indicators should both come ON steady at this time. If either indicator comes ON before the reset switch is
opened, disconnect the input power and check all wiring. Return to step 2 after correcting the problem.

6. Cause the safety device to generate a STOP or "open-contact" state (for example, actuate the E-stop switch to open its contacts).The

Ch1 (K1) and Ch2 (K2) indicators should turn OFF simultaneously. If either indicator remains ON, disconnect the input power and
check all wiring. Return to step 2 after the cause of the problem has been corrected.

7. If more than one safety device is series-connected to the Safety Module, run the above checkout procedure individually for EACH

device.

8. Close and secure the enclosure in which the Safety Module is mounted. Apply power to the machine control elements and perform

the Periodic Checkout Procedure.

WARNING: Multiple Safety Devices
When two or more safety devices are used, each device must be individually actuated, causing a
STOP or open-contact condition, then reset/rearmed and the Safety Module reset (if using manual
reset mode). This allows the monitoring circuits to check each device and its wiring to detect faults. Fail-
ure to test each device individually in this manner may result in undetected faults and create an
unsafe condition which may result in serious injury or death.

A Designated Person is identified in writing by the employer as being appropriately trained to perform a specified checkout procedure.
