13 PERIODIC MAINTENANCE
Periodical maintenance is reduced thanks to minimisation of wearing parts (no brushes,
only one optional power contactor). So the periodic maintenance may be limited to the
following checks. Perform every three months:
1) Check main remote control switch contact wear. Replace when contacts are worn.
2) Check mechanical movement of main remote control switch contactor. It must be
free and not jammed.
3) Check power wiring going to the battery and steering motor. The terminal must be
tight and firmly connected. The insulation must be sound.
4) In the prEN 1175-1 directive compliance, check the operation of the fault detection
circuitry (see par. 13.1).
All work must be performed by qualified trained personnel. All replacement parts must
be genuine OEM parts.
Any potential problem discovered by the service technician periodically checking the
equipment that could lead to additional vehicle damage must be communicated to ZAPI
technical staff or the technical sales network so that corrective action and an
appropriate decision regarding continued operation of the equipment can be made.
If a user detects a steering problem, it is the user's responsibility to remove the truck
from service, tag it, and notify a service technician for corrective action.
13.1 TESTING THE FAULT DETECTION CIRCUITRY
The material handling directive prEN 1175 requires periodic testing of the controller's
fault detection circuitry to be checked in one of the following modes (choose your
preferred):
1) Switch on the key and try to disconnect the tacho-generator (or the stepper motor
channels). An alarm, stopping the traction should immediately occur.
2) Try to disconnect the steering motor. After switching on the key an alarm stopping
the traction should immediately occur as soon as the tacho-generator or the stepper
motor rotates.
IN THE EVENT OF TROUBLE WITH ELECTRICAL EQUIPMENT MAKING IT
DANGEROUS TO USE THE VEHICLE, THE USER MUST NOT USE IT.
