VC-W MR2 (integral racking)
EATON www.eaton.com
E3: Motor timed out
Condition when motor continues to run in excess of 45 seconds
during racking process . This error state condition can be caused
from a broken motor shaft, coupling, or a damaged gear box .
Operator should shut off power to the VC-W MR2 controller
by tripping the 15 A circuit breaker (see Figure 11 ) in the LV
compartment and manually rack out the MV device . Once the
MV device is removed from the compartment, the operator can
replace the damaged devices .
E4: MV device position “unknown”
Controller does not know the location of the MV device in the
breaker or auxiliary compartment . The operator must press the
“Disconnect” button on the pendant as the other buttons will not
function . Once the breaker has reached the disconnect position, the
“Disconnect” LED will illuminate and the operator can start the MV
device racking process over by pressing the “Connect” button .
E5: Open permissive
This state is due to a permissive contact being open . It could be a
standard permissive such as the circuit breaker being closed or the
slider bracket being pushed in . In this case, press the “Disconnect”
button to reset the controller . Once the permissive switch is closed,
any operation will work . Use troubleshooting guide as shown with
Figure 1 and 2.
E6: Communication error
This state results from damaged communication cable or wiring .
Check all areas of communication wiring (e .g ., discrete, CAT5, TB
wiring, or Modbus controller wiring) . If disconnect and connect
positional circuits are closed, the board enters programming mode
causing a communication error .
E7: No MV device
This state occurs when the Lev-in assembly racks in and the
“Connect” limit switch is depressed; however, no increase in
motor current is detected . See below table for normal operating
current values .

5/15 kV Arc Auxiliary — —
5/15 kV Non-arc Auxiliary — —
E8: Firmware compatibility error
This state results from the pendant and controller card not having
compatible firmware . Contact your Eaton representative to have the
firmware updated .
E9: No test (MR2 open/close only)
This state occurs when the test button is pressed and the control
board does not have test activated . See Figure 2 . There is not a test
position available for the MV device .
Controller diagnostic display
This feature can be used for diagnostic and troubleshooting
purposes . The operator will press and hold down the enable button
while pressing and holding down the unused button under the
“Intermediate” label on the pendant for 3 seconds . The Gear type,
controller firmware version, pendant firmware version, rack-in count,
rack-out count, overcurrent count and “test” or “No Test” verification
will scroll across the display .

9 . MODBUS Address (01 to 99)
Each new version of the firmware will be an increased revision of
that firmware in our system . There will be no rev 2 .1 then rev 2 .2,
it will go from rev 2 to 3 to 4 and so on for any change made to the
firmware .

CAUTION
SETTING THE WRONG GEAR TYPE CAN CAUSE THE BREAKER TO NOT
FULLY RACK IN. GEAR TYPE IS CELL SPECIFIC, IF A CONTROL BOARD
IS MOVED TO A NEW CELL ONE MUST VERIFY GEAR TYPE USING
CONTROLLER DIAGNOSTIC DISPLAY.
Setting the gear type
All gear types are imbedded in one controller firmware version . The
gear type is set with defined inputs on power up . Gear Type may be
set by one of the two methods shown below . If Method 1 is used it
will override any Gear Type set using Method 2 .
Gear types
01 5/15kV 1200, 38kV 25kA *
02 5/15kV 3000A
03 5kV narrow design
04 27kV
05 5/15kV 2000A, 38kV 40kA
06 Arc aux (ignores E7)
07 ¼ high aux (ignores E7)
15 Demo (ignores E7)
* 5/15 kV 2000A switchgear cells built prior to 2019 used Gear Type 01.
Method 1 , applies to pendant with enable button .
The gear type is set by turning the Gear Type Dial to correct gear
type shown in the table in the previous section (Note: Gear Type 15
is position F on the dial) . The gear type can then be verified with the
diagnostic display .
