2.1 Mains connection, Fuses, Frequency controller and
travel recognition PCB
2.1.1 Check main supply on main control box
a) Single phase controller: Incoming tension
Measure between terminals:
b) 3-phase controller: Incoming tension
Measure between terminals:
 If you measured these values, proceed to point 2.1.2
 If not, search for faults within the mains supply ( RCD, Fuses, Wiring, …..)
L1 – N = 230 V
L1 – PE = 230 V
N – PE = 0 V
L1 – L2 = 400 V
L1 – L3 = 400 V

2.1.2 Check fuses
Switch off main switch, execute the work mentioned, switch on the main switch again
a) Fuses F1 and F2
Check whether tripped or not – press them in, if required
b) Fine-wire fuses on PCB
Take them out and check them for contuinity
 if ok, proceed to point 2.2
 if not, proceed to point 2.1.3
F1 / F2
2.1.3 Fuse blown or loose
a) Fine-wire fuse blown (on PCB)
- Check terminal 37 – 38 for continuity – if continuity, proceed to point 7
- Check isolating hose on end of support rope for damage or blank section (rope end
shall not make any metallic contact with parts like the guide rail or carriage).
Only if you have checked these points and they are ok, you may insert new fuses and
switch on the controller
Refer to the installation manual for correct placement of support rope end
b) If always a contactor trips when you switch on the controller, check wiring of safety circuit I
and II (Terminal 1 – 16 and 16 – 32) as well as its switches and relays K11, K22 and K3
for short circuit.

2.2 Check frequency converter (FC) (if applicable)
Check whether the LED is blinking (not when you are
switching on/off the controller) (depending on the type
of FC you need to take off the cover) or if the error
code 33”WARN FU” appears in the display.
If this is the case, proceed to point 2.2.1, otherwise to
point 2.3
2.2.1 Fault remedy on FC
When the controller is switched off (min for 20 sec),
and switched on again, a failure reset takes place.
Whether the fault does not appear again is uncertain
as the cause can could be on the motor, its wiring or on the brake
 Check motor (e.g. corrosion on terminals, water leaks, short circuit on motor housing) as
well as the brake for proper function and its wiring for damages.
If the FC fault is caused by overheating, the FC needs to cool down completely (this might
take sometimes several hours) ! Then the FC will be started up again in a state where he can
act again properly.
 If this has been checked and everything is in order but no result has been achieved,
change the FC.
2.3 Check the travel recognition PCB
Switch off main switch, execute the work mentioned, switch on the main switch again
Unplug the 2 connectors
Check whether the fault is still present
If fault still present, plug in the
connectors again and proceed to point 3
If not, exchange the travel recognition PCB

3.1 Check setup
Check the setup menu for correct adjustments against the specification sheet (FO3161)
Encoder
Turn encoder till the menu “Setup” Turn the encoder and check whether
appears - then press it parameters comply with the
specifications
 if parameters comply, proceed to point 3.2
 otherwise proceed to 3.1.1
3.1.1 Reprogram “setup” parameters
Obviously, different parameters were found. You need to investigate the reason (new
requirements of the client; technical modifications; ….) for if they have not been already
mentioned on FO3161 in the column “changes”.
Unless there are reasons, reprogram the controller acc to the specification sheet FO3161.
For programming respectively reprogramming refer to FO3161.

4.1.2 Communication with call stations
Take off the front cover of the call station which does not show communication
Check whether call station code complies with the number of the landing
Check whether LED’s are lighted permanently
If this is ok, take off the call station completely and connect it directly to the main controller
 if function ok: wiring faulty

5 Check safety circuit I and II
Check the safety circuit along:
- Safety end limit switch top end
- Arrestor / overspeed governor
- Safety end limit switch bottom (if applied)
- Slack rope (if applied) (for drive 400 only)
- Drive cabinet door switch (if applied)
for continuity.
To check: Take off wire from terminal 1 and 16 (make sure other wires stay in place !!)
Measure continuity from the 2 taken off wires.
 If continuity: proceed to point 6
 if no continuity: Check switches and its wiring for faults (use diagram)
You might also bridge the safety circuit but bear in mind that you create a dangerous
situation:
- Take off the arrestor pawl (support rope might be damaged)
- Safety end limit switches out of operation (carriage could overtravel –collosion
between rail end ad carriage – worst case: damage of upper trolley and rope !)
 apply a bridge between 1 – 16
if the installation runs, then, the fault has to be within the bridged circuit !

Switch off installation by the key switch on the call station (LED OFF).
Turn the encoder till “FZ/RS Status” appears
Press the encoder to reach the sub-menu and turn it to reach the status of the single call
station (RS)
If everything is ok, the display shall show the same for

If one of the indications above appears, even the relevant button is not activated, take off
the wire on the switch (not on the emergency stop – see diagram) and check again the call
station (RS) status. If the display of that has disappeared, change the button
7 Status of carriage (FZ)
7.1 Test carriage status
Switch on installation by the key switch on the call
station (LED lighted).
Turn the encoder till “FZ/RS Status” appears - press
Turn the encoder till “fz0:” appears
7.1.1 Check drive order from hand hold control unit on carriage
Check whether this sign appears “
^’”
If this is not the case, go to 7.1.2
If it is the case, check whether one of the directional
buttons is pressed. If not, unplug the hand hold control unit and check again. If the
symbol does not appear, the fault must be on the control unit or on its wiring.
7.1.2 Check safety switches on carriage
Check whether this sign appears “
>2”
If this is not the case, go to 7.1.3
Otherwise check whether the carriage has run into an obstacle or into the floor.
If not, go to 7.2.1
7.1.3 Check landing recognition of carriage
Check whether the controller recognizes the
landing where the carriage is located
1 = number of landing
If ok, go to point 8
If not, check position of code-cams on landing plates.
Glide with a screw driver along the proximity switch to simulate a landing !

7.1.4 Check platform position of carriage
Check whether the controller recognizes the various positions of the platform.
Run the carriage onto a landing (maybe hand winding required)
Press the emergency stop (display changes from “ok” to “em”)
Now, fold up the platform (no damage will occur !)
Check the display for “PFZu”
Fold fully down the platform (leave the barriers down)
Check the display for “PFzws”
Fold up barriers (as if a user would like to board).
Unlock the emergency stop
Switch off the main controller for at least 20 sec. And switch it on again
Press one of the directional buttons on the hand hold control unit in direction to the
travelway end (if carriage on a mid-landing, press the open barrier button).
Check the display for “PFZus”
Travel a bit away from the landing (maybe hand winding required) and do the same thing
again. In this case, it does not matter which travel directional button you press.
Check the display for “PFTrsp”
If ok, proceed to point 8, otherwise to point 7.2.2

7.2 Search for faults
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
