2.10 Emergency Shutdown
In the event of an emergency or malfunction, press the E-Stop button. The UV-9 Cure Module has two E-
Stop buttons. The E-Stop buttons are the large red buttons located on the operator’s front control panel
and one at the rear of the oven (Figure 2-5). Activating the E-Stop immediately halts conveyor movement
and turns off the UV lamp.
WARNING! CAUTION!
The E-Stop buttons do not cut power to the equipment. Do not restart the
equipment until the condition that caused the emergency shutdown has been
corrected. Failure to comply could cause serious injury to the user and/or serious
damage to the oven.
TIP If the operator or technician is unable to reach the E-Stop button, the Main Circuit
Breaker (Figure 2-5), which is located on the back of the system, can be used for
emergency shutdown.

system. Refer to 5.4 System Startup for instructions.
To recover after an emergency shutdown:
1. Clear the conveyor of all workpieces.
2. Lock out/tag out all system power. See 2.12 Lockout/Tagout of Electrical Energy for
specific details.
3. Locate and remedy the cause of the emergency shutdown. See Section 7 – Troubleshooting
for more details.
4. Reset the Main Circuit Breaker inside the electronics enclosure if it has been tripped.
5. Turn the red E-Stop button clockwise until it pops back into position.
6. Remove all warning tags and locking devices.
