Safety Devices and Guarding
Note: The safety features should NEVER be bypassed, disabled or tampered with.
Precision Valve & Automation, Inc. is not responsible for any damages incurred
because of alteration or destruction of any safety features.
Safety Circuit
236BThe machine main power is controlled by the safety circuit with a safety relay and
additional safety devices. The safety relay has a redundant and self-checking circuit,
which means two parallel relay circuits work together electrically with the safety devices.
The tripping contacts of the relays are connected in series to make sure the safety circuit
will disconnect the power even if one of the relays fails. The self-checking circuit has
positive guided contacts, mechanically forced to operate together. If one of the redundant
relays fails, the power contacts are opened. The safety devices monitor the state of the
Emergency Stop button and other safety mechanisms. When one or more of the safety
devices have opened, the power is stopped.
Work Area Access
237BThe work area is enclosed with Lexan guarding or safety glass.
Door
238BThe top of the machine is protected by a door. The door is monitored by a non-defeatable
limit switch. The Door Bypass key is for maintenance access only.
Light Tower Operation
239BThree stacked indicator lights and a buzzer are used to indicate the status of the machine.
The lights are visible from all sides of the machine and operate as follows:
•
94BThe green light is on when the machine is in Auto Cycle and producing parts. It is
off at all other times.
•
95BThe amber light is on when the machine is in Auto Cycle, but cannot operate
because of an external material handling problem (no incoming parts or no room to
unload parts).
•
96BThe red light is on steady when the machine is not in Auto Cycle due to operator
intervention. It will flash when the machine is in cycle, but the cycle has stopped
because of a machine problem. It will be off at all other times.
•
97BThe buzzer will cycle with the red light during machine errors.
