Condition Cause of Fault / Action Required
1 Start machine
0 1 Normal
¾
Continue to step 2.
0 0 Normal ¾ Continue to step 3. 2 Press SET button
0 3 Fault
¾ Check that transmitter and
receiver are aligned and laser is
clear of any obstructions. Press
SET button.
Beam travels short distance then
stops. Hydraulic pump may be
shut down.
0 0 Normal
¾
Continue to mute point set-up
Section 8.5.
Beam travels short distance then
stops. 0
1 Fault
¾ No encoder movement detected
during secondary stopping
TEST. See fault 1.
Beam does not move
0 1 Fault
¾ Start time exceeded. No
movement detected within 1
second of the approach input
turning on. See fault 1.
Beam travels short distance then
stops. System shuts down.
8/2 Fault
¾ No approach input signal to LZS-
003 controller. See fault 2.
Beam travels short distance then
stops. System shuts down.
9./1 Fault
¾ No approach input signal to LZS-
003 controller. See fault 2.
Beam travels and stops when
laser is obstructed
0 3 Fault
¾
No approach input signal to LZS-
003 controller. See fault 2.
Beam travels and does not stop.
System shuts down.
8/2 Fault
¾ Stopping distance error -
Secondary Stop. See fault 3.

¾ Reverse encoder A and B
channels
8.4.1 Initial Start-Up Test Faults
Fault Description Check
¾ Check encoder wiring connections to the LZS-003 controller.
¾ Reverse encoder A and B channels
¾ Check mechanical operation of the encoder. Check the optical encoder sprocket is firmly
secured to the encoder shaft. Check the optical encoder chain and spring travel.
1 No encoder movement detected
during initial start-up TEST.
¾ Replace the encoder
2 No approach input signal to LZS-003
controller. ¾ Refer to the LZS-003-HS Installation Manual
¾ Machine has exceeded the maximum allowable stopping distance.
¾ SEC 1 & 2 contacts not connected in best location to ensure adequate stopping distance.
¾ SEC 1 & 2 contacts not connected where they will cause the machine to stop.
3 Stopping distance error - Secondary
Stop
¾ Reduce machine approach speed to allow stopping within maximum allowable limit
