7.2.1 Safety switches
“< , v, > “ Identifies a safety switch within safety circuit 1.
The controller recognizes the single switch.
“ 2 ” Identifies a safety switch within safety circuit 2.
The controller recognizes only safety circuit 2.
Check
safety switch (switch test):
Switch OFF controller on main switch
Change Dip switches 6 and 8 on carriage PCB to ON
Switch ON controller on main switch
Activate with a screw driver all safety switches in safety circuit 1 (beep = this switch ok !)
Activate now one switch of the safety circuit 2 (beep = all switches ok !)
If no beep circuit 1: check the switch in detail and its wiring (check also diode built into
loom of S14/S15)
If no beep circuit 2:
Switch OFF main switch
Unplug looms on carriage PCB
Check all single switches within circuit 2 with a continuity checker.
If no continuity – change the switch
7.2.2 Position switches
The controller needs to receive the correct information as to define the state of “PFTrsp”,
“PFZus” and “Pfzu” – otherwise the controller shows “PFzws”.
Check
position switch (switch test):
Switch OFF controller on main switch
Change Dip switches 6 and 8 on carriage PCB to ON
Switch ON controller on main switch
Activate with a screw driver all position switches (beep = this switch ok !)
If no beep: check the switch in detail and its wiring
