FAQ (Frequently Asked Questions)
|
Q |
Will the ZM6 work OK with LifeP04 battery bank |
|
| A | Yes as long as the charge voltage is set well below the BMS upper voltage setting,we have heaps of customers using this setup | |
|
Q |
What wiring changes are required on my existing installation? |
|
|
A |
As well as running a wire to your alternator field terminal, you will need an ignition source to the ZM6 and a battery positive and earth. |
|
|
Q |
Will this unit work through a VSR (Voltage Sensitive relay)? |
|
|
A |
Yes. A good way to allow dual battery charging, sense off the house battery. |
|
|
Q |
Will this unit work through a diode splitter? |
|
|
A |
Yes. The ZM6 can compensate for the typical voltage drop over a diode bank, providing that the battery sense wire is on the battery side of the diode bank. |
|
|
Q |
Can you refurbish my alternator and convert it to an external regulator? |
|
|
A |
Yes, we do this regularly for clients. |
|
|
Q |
Can I modify my alternator? |
|
|
A |
Yes. It is a matter of running a field wire to the appropriate side of the brush block. The ZM6 N controls the earth side of the brushes. The ZM6 P controls the positive side of the brushes. |
|
|
Q |
What is the difference between N and P switching |
|
|
A |
Certain manufacturers elect to switch the positive brush whilst the majority of others switch the negative brush, as a user you do not know the difference in an operational sense. |
|
|
Q |
Why does the RED LEDs glow slightly during operation. |
|
|
A |
As the voltage/temperature near the trigger threshold the LED will glow slightly, this is normal and nothing to worry about. |
|
|
Q |
There is an Green LED flashing on the inside of the unit? |
|
|
A |
This LED flashes with the onboard oscillator which will run when in Absorption mode, it is normal and for fault-finding purposes. |
|
|
Q |
What is the field LED function and will it indicate a blown fuse on the field line? |
|
|
A |
The purpose of the field LED is to indicate that the ZM6 microprocessor is outputting a field current. It is located downstream of the fuse so will NOT indicate a failed field fuse (5 amp) |
|
|
Q |
The unit is powered up and the system does not charge and there are no fault LED’s on nor is the field LED on |
|
|
A |
Push the clear button or reset ignition, a previous fault has shut down the system and requires resetting. If you have the buzzer connected this will sound until you clear the fault |
|
|
Q |
After start the unit goes into fault mode and as soon as I clear the fault it works OK |
|
|
A |
During the start cycle the battery voltage is dropping below 10 volts and this is the trigger point for low battery threshold, there is a fix with a timer unit to delay the start, this is the cheaper of the two possiblities being faulty start battery or high resistance cables and or a bad earth |
