Safety Devices and Guarding
The DeltaTherm IR Cure Module has safety features that protect the operator from hazards
during normal operation of the machine.
Note: Do not bypass, disable, or tamper with the safety features. Precision Valve &
Automation, Inc. is not responsible for any damages incurred, mechanical or human,
because of changes or destruction of any safety features.
Safety Circuit
The main power to the machine is monitored and controlled by the safety circuit. The
safety circuit has a control relay and one or more safety devices. The tripping contact of
the relay will disconnect power if the relay fails. Self-checking consists of positive guided
contacts which are mechanically forced to operate together. If the relay fails, the power
contact will open. The safety devices monitor the state of the EMERGENCY STOP button
and other safety mechanisms. When the safety relay detects that one or more of the safety
devices is open, the power to the motors and pneumatics is stopped.
Doors
Access to the machine is provided by two doors. Modules have door protection through a
non-defeatable limit switch. The IR panels are disabled if a door is open.
