XL1500 Safety System
Safety Loop on the Machine
The safety system on the machine is based on a 24 VDC
1. 24v loop comes from the 24v P.S.
2. The loop passes through the head carriage E.S sensors (on the head carriage frame) right and left E.S, rear E.S laser relay and to the pneumatic panel.
3. The loop continues to the Over flow board and to theInk system relay.
4. Ink board receives the 24vdc and operate the ink system.
5. The Rip2CCB receives the 24vdc and transfers it to the motion controller.

Safety Loop on the Machine (Cont.)
6. The loop passes through the free fall service switch, if it’s in Service position – the drivers shut down and the loop continues to the laser Assy and making a shortcut between pins 14 and 21.
7. If the service switch in not in Service position – the loop continues and the +24vdc passes to the K3 contactor inside the PDU.
8. Together with the –24v, it comes directly from the 24v P.S, enabling the K3 contactor and the motion system to work.
9. A signal comes out from the PDU (K3 contactor) to the motion controller, which, in turn, gives a signal if there is an emergency interrupt.
10.Right and left limit switches close a loop on the motion controller (inputs only – pins 2 and 10 on J5) – if the loop is open – Print will not be performed.

E.S. Circuit Operation
1. Motion system
Power of 220V to drivers X, Y, Z, T is cut off.
Emergency circuit in motor controller is turned on, and the drivers are disabled.
2. Pneumatic system
24V for pneumatic panel is turned off
Z-shaft moves up immediately
Roller pressure moves down immediately

Automatically Activated Safety Features
1. Head carriage movement freezes when:
An obstacle blocks the motion protecting frame
The cover is removed
One of the doors (side door, front door) is open
Mounting one of the night covers
Note: Heads Carriage Safety frame is attached to the E.S circuit from machine 2023.
2. The heating system shuts down when:
The temperature in the hood rises above 120º
The fans are not supplied with Electricity
