Exit Options
You can bring up this options menu by holding your
finger down on the screen for 1 second. From here you
can do a manual reset of the State of Charge (back to
100%), enter the Setup mode, or switch the display
off.
When the display is off, touch and hold anywhere for
1 second to turn it back on. Display will automatically
wake if there is a new warning to display.
Setup mode can only be entered from Idle state, i.e
when the vehicle is not charging or being driven.
Configuring Settings
The EVMS Monitor can be used to configure settings for all ZEVA devices on the CAN bus.

The Setup mode has three rows. The top row
toggles between the General Settings and the BMS
Configuration sections. Tap the arrows either side to
navigate between these. In the General Settings page,
the second row selects the parameter to be modified,
and the third row modifies the parameter itself. The Exit
Setup button will distribute new settings to all devices
on the CAN bus then return to normal operation.

This page is for configuring your battery pack (so the
BMS knows how many cells to monitor).
Tap the arrows either side of the Module ID row to
select the module in question, and the arrows either
side of Num cells are used to modify how many cells
that BMS module should expect at that ID.
List of Settings
The following table describes the parameters available in the General Settings page. The
number of settings can be a bit overwhelming at first, but most of them can be left at their
default value unless you need to adjust a specific function to suit your installation.
If you wish to lock the settings after the system has been commissioned, simply remove the
small jumper on the left-hand side of the Monitor’s CAN port. (The right-hand jumper is for
disconnecting the Monitor’s internal CAN termination resistor, in cases where the monitor is
not at one end of the CAN bus.)
Name
Range
Description
Pack Capacity
5-1250Ah
The rated capacity of your traction battery pack,
in Amp Hours.
SoC Warning
0-99%
The EVMS can raise a warning when the traction
battery’s SoC reaches a predetermined level.
Use 0% to disable.
Full Voltage
1-400V
The EVMS uses a “full voltage” threshold to
detect charge approaching completion. One
hour after reaching this voltage, the EVMS will
reset the SoC to 100% and power down.
Warn Current
0-1200A
The EVMS will provide a warning if the current
in the traction circuit exceeds this threshold. Set
above 1200A to disable.
Trip Current
0-1200A
The EVMS will provide a warning and
automatically shut down the traction circuit if
current exceeds this threshold.
EVMS Temp Warning
0-150C
/ OFF (151)
The EVMS will provide a warning if its
temperature sensor exceeds this threshold.
It will not shut the vehicle down, but it is
recommended that you stop to investigate as
soon as possible. Note that this is independent
from BMS temperature sensors and warnings.
Min Aux Voltage
0-14V
If the 12V supply drops below this threshold
for more than 5 seconds, a warning will be
provided. It may indicate a weak 12V battery
and/or faulty DC/DC converter.
Min Isolation
0-100%
A warning will be raised if isolation integrity
from traction circuit to chassis drops below this
threshold, indicating compromised insulation
or an unexpected conduction path. See also
section on Isolation fault detection.
