Safety Device Lock-Outs
Some safety devices disconnect electrical energy from a circuit. The safety devices that are
used in this Controller are primarily concerned with electrical power disconnection.
WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing the 4-Pump, 38-Station Controller. Failure to do so may result
in serious injury. No one but the person who installed the lockout may remove it.
