TL;DR
Find which E-stop button is depressed (operator panel, side door, or remote), reset it, then clear the alarm from the Mazatrol screen.
What you might see
- Mazatrol alarm 4
- EMG stop
- cycle start blocked
Likely causes
Operator panel E-stop pressed
Side-door E-stop pressed
Remote E-stop pressed
Wiring fault on the E-stop chain
Safety first
- Do not bypass the E-stop chain to clear the alarm.
Procedure
- 1
Check the operator panel, twist any depressed E-stop button counter-clockwise to release.
- 2
Walk around the machine and check the side-door and rear E-stop buttons.
- 3
Press CLEAR or RESET on the Mazatrol pendant to acknowledge the alarm.
- 4
If the alarm immediately reappears, the E-stop chain has a wiring fault, call electrical maintenance.
Stop fixing the same fault twice.
