FAULT CODES
Battery flat during upward movement F5
Check battery voltage individually. Press directional switch to change F5 to E7,
and drive down to the closest charge point to recharge the batteries. E7 will clear
automatically once the batteries has reached a safe charge to drive.
Final limit switch overrun F6
If the lift has over travel its parking position at the top or bottom of the rail, check

FATAL ERRORS CONTINUED
HARDWARE ERRORS
Feature T700 A130
Safety grounded to chassis (SW1 safety circuit) H1
One or more switches from the SW1 safety circuit is grounded to chassis.
Check continuity between every switch in the SW1 safety circuit and chassis
Safety grounded to earth (sw2 safety circuit) H2
One or more switches from the SW2 safety circuit is grounded to chassis.
Check continuity between every switch in the SW2 safety circuit and chassis
Auto Hinge communication fault H3
Reset the hinge control box using the reset button. Check power supply and
battery back up in the hinge control box. Paired PCB and hinge control box again.
If the problem persists, replace the hinge control box.
Secondary processor U2 not responding H4
Reset PCB. If the problem persists, replace the PCB.
Memory store not responding (EEPROM) H5
Reset PCB. If the problem persists, replace the PCB.
Auto Hinge end limits not found (timeout) H6
After 60 seconds operating, the folded switch or the interlock switch circuit
remained open. Check every connections between the hinge and hinge control
box and the operation of the micro switches.
Heat sink over temperature H8
Allow the lift to cool down. If the problem persists, replace the PCB.
Main Motor PWM fault H9
Reset PCB. If the problem persists, replace the PCB.
