Code C28 - Main ON/OFF Switch Warning
Transistor controller could not be reset via the CAN-bus at power ON or transistor controller reports main ON/
OFF switch is open.
Truck functions are not allowed after code has been set.
This code can only be cleared after the problem is resolved and truck is turned OFF and back ON.
1. Main ON/OFF switch activated.
2. Low voltage to transistor controller (especially while lifting or driving) due to overcurrent or short circuit.
a. Try driving using a known-good battery.
3. PTC R1 missing, bad, or tripped (very high resistance, due to excessive current while main contactor is
open; should automatically recover.)
a. Carefully check to see if R1 is hot (tripped); if so unplug battery and allow it to cool. Locate low
impedance path that tripped R1 and correct.
4. Wire #24 at OV.
a. Check that J5 is connected, fuse and wiring.
b. Check for 24V at J5-16.
5. Short or open circuit in CAN wiring or electrical noise in CAN wiring due to bad connection or outside
interference, both at power ON.
a. Check CAN wiring.
b. Try operating truck in different environment.
6. Bad transistor controller.
Code C29 - Time to Service Warning
See service parameter 25 on page
None.
See service parameter 25 on page
1. Time for service.
2. Service interval not reset after last service.
Code C41 - Battery Undervoltage Warning
Voltage at transistor controller B+ connection less than 17V (when main contactor is closed.) Low voltage can
also cause problems such as electrical components not powering up / staying activated and CAN errors.
Truck functions are allowed unless the voltage was below 13V, in which case the truck must be restarted (Code
C28) may be displayed.)
Code is cleared when voltage recovers.
1. Low battery voltage.
a. Check for proper voltage; charge battery if necessary.
2. Battery parameter not adjusted correctly.
3. Circuit breaker has opened due to overloading or short circuit.
a. Check brake adjustment (see
4. Open circuit to transistor controller B+ connection.
a. Check cabling.
5. Bad transistor controller.
