34 SLC 500

™

Isolated Analog Output Modules

Standing Clear Of Machinery – When troubleshooting a problem with

any SLC 500 system, have all personnel remain clear of machinery. The

problem may be intermittent, and the machine may move unexpectedly.

Have someone ready to operate an emergency stop switch.

CAUTION

POSSIBLE EQUIPMENT OPERATION

Never reach into a machine to actuate a switch. Also,

remove all electrical power at the main power disconnect

switches before checking electrical connections or inputs/

outputs causing machine motion.

Failure to observe these precautions can cause personal injury

or equipment damage.

Safety Circuits – Circuits installed on machinery for safety reasons (like

over-travel limit switches, stop push-buttons, and interlocks) should

always be hard-wired to the master control relay. These circuits should

also be wired in series so that when any one circuit opens, the master

control relay is de-energized, thereby removing power. Never modify

these circuits to defeat their function. Serious injury or equipment

damage may result.

Refer to your system’s Installation & Operation Manual for more

information.
