Power System
Power System Access
To access the battery, power cord, power module, and wiring, remove the (6) Philips head screws surrounding the base:
The power cord can be replaced after removing the rear screw and lifting the access panel.

PowerVar Inverter
The inverter is secured to the base of the cart by (4) Philips head screws at the base.

The front panel has the termination points for the power/status panel, the battery communications cable, and the
power connections to and from the battery and cart.

Power-Sonic LiFe Battery
The Lithium Iron Phosphate battery is secured by the foam that it is set in. The wiring to the battery terminals should be
disconnected before the battery can be removed.
The red fuse holders contain a 40A fuse between the battery and power module, and a 10A fuse between the battery
and lift control relays.

Components
Lift Mechanism
The lift control board is located in the box underneath the worksurface, on the back of the lift column.
Lift motor connector (P1)
30A Motor control relays
Lift Control switch
connector (RJ45 –P2)
Red/Black 12V power

Power Cord
The power cord can be easily replaced after removing the access panel screw at the rear of the cart base. Compress the
cable retention insert and pull it out.

Troubleshooting
NOTE: PowerVar’s MPMView software is crucial for troubleshooting power system (inverter/charger and battery)
issues.

Basic Troubleshooting
Problem
Possible Cause
Action you should take
MPM does
not power up
and has no
audible alarm
On/Off button is not pressed long
enough
Press and hold the On/Off switch for
at least 3 seconds.
Invalid Battery and Invalid Input
AC.
Check wall socket and test for
proper line voltage.
MPM input power cord is not
plugged in
Plug in input power cord
Output fuse is open
Reduce load replace fuse and test
Backup time is
less than
expected
Battery is not fully charged or
battery is worn out.
Recharge battery for at least 24
hours and retest backup time.
MPM seem
normal, but the
load will not
turn on.
power cord is loose or not
connected between MPM output
and load.
Connect computer input power cord.
The MPM indicates the presence of Warning (yellow) and Severe (red) Alarms and Conditions via the RUI
(Remote User Interface) and via the Clinic View taskbar application.
“1/4Full” LED provides Low Battery indication

Low Battery Conditions
Low battery (yellow) Low-battery-critical (red) conditions will flash the LED in the “1/4tank” position, yellow or red according to
the severity… Low battery threshold conditions will also cause the Clinic View application to open automatically to notify
the cart user of the time remaining and charge level.
Service Related Conditions
Service related alarms, such as overload, over temperature, replace battery etc., will cause one of the RUI
Service LEDs to flash.
The specific alarm that is raising the Yellow or Red status will be logged and displayed locally in the Tech View
application.

Table of Condition codes
The table below lists the specific conditions and what they mean. The “Code” is the number included in the Event
Log alarm description.
Code
As displayed in MPM View
What it means
24-034
Battery Charge
Threshold: Low
1st level warning for low battery charge level. Is triggered
when either threshold for % charge or estimated minutes is
reached. Default thresholds are 7% or 5 minutes. These can
be modified with MPM Tech View.
20-147
Lost Device Communications
MPMView is unable to communicate with MPM unit. This
could be caused by the USB cable being disconnected, the USB
port on the computer has failed or the MPM is off. It is not
likely that the MPM will be off in normal usage, however it is
possible in lab settings when PC running MPMView is not
powered by MPM.
24-050
Service Check: Battery
Parameters not Initialized
Alarm raised when the MPM is configured to detect a
smart battery but is unable to establish communications
to the battery. The MPM would then be operating in
Smart Discovery Mode at reduced charger current.
Remedy: Configure the unit for the actual battery
attached using MPM Tech View software.
24-051
Service Check: Replace Battery
–Health Threshold
Raised when the measured battery capacity is less than x%
of original design capacity (measure of state of health).
Defaujlt is 50%, configure the threshold via MPM View.
24-063
Service Check: Replace Battery
–Date Threshold
Raised when the comparison of MPM View system date to
Battery Replace Date indicates that the battery Age is older
than the Battery Age Threshold. Default is 18 Months,
configure via MPM View.
24-064
Service Check: Smart
Batteries –Configuration
This alarm is raised when the number of smart batteries
detected is different than expected by MPM configuration.
24-066
Service Check: Smart
Batteries - Communication
Raised when MPM unit has lost communication with a
Smart Battery. Could indicate Smart Battery has entered a
Safe/Protect Mode and turned itself off after being left
depleted and without charge for too long. The alarm may
clear if the MPM unit is able to recover the battery.
If the alarm persists, check Smart Battery cable connections
20-134
Service Check:
Temperature Warning
This is the 1st level warning that the MPM internal
temperatures are nearing a level where immediate thermal
shutdown could occur if temperatures continue to increase.
Check that MPM ventilation is unobstructed. If no visible
obstruction, MPM unit may need cleaning or other Service.
24-032
Service Check: Battery
connection
The MPM unit detects no voltage across the battery
terminals. Battery may be disconnected, or there may be a
blown fuse. The MPM can still power up.

Code
As displayed in MPM View
What it means
30-189
Input frequency out of range
This alarm is raised if the frequency of the input AC power to
the MPM unit is out of range and the output can only be
supplied from battery power.
30-190
Service Required:
Output Bad
MPM detects a problem in inverter or output circuits; output
relay is shorted, inverter voltage too high or too low, inverter
failure or output fuse open.
30-192
Service Required: EEPROM
failure
MPM detects a serious internal error. Return for Service.
33-037
Service Required: Charger
Raised if MPM charger delivers more than 110% of max
charge current for more than 60 seconds.
33-038
Service Required: Charger
Raised when MPM is attached to a Smart Battery and battery
indicates an “Over Charged” alarm.
34-053
Battery Charge Threshold:
Low-Critical
Final warning to recharge battery –shutdown imminent.
Hard coded within MPM to be raised when charge level is
less than 5%.
34-055
Service Warning: Smart
Battery Over Temp
Raised when MPM is attached to a Smart Battery and battery
indicates its internal temperature has exceeded internal
threshold.
36-080
Output Overload
This alarm is raised if MPM detects its VA output is over 110%.
36-081
Output Overload
This alarm is raised if MPM detects its Watt output is over
110%.
