ELECTRONIC TROUBLESHOOTING E-78 & E-88

Power Down Sequence:

1. RCM Press power button for three seconds.
2. HCM This  device  will  remain  connected  to 
battery.
3. PCM  This  device  can  remain  connected  to  main 
plow plug.

Plow

If plow is Dismounted – Plug in power cable at Plow, 
Press  Mount  Switch  until  mounting  is  clamped 
completely. Go to 

A.

If plow is already mounted – Plug in power cable at 
Plow. Go to 

A.

If plow is already mounted and plugged in. Go to 

A.

NOTE:

  Mounting/dismounting  is  active  for  a  20 

second period after power cable is plugged in. The 
headlights will flash at end of this 20 second period 
to  indicate  Mount/Dismount  is  ended.  If  Remote  is 
powered ON while in mounting/dismounting, lights will 
flash immediately and system will go out of mounting/
dismounting mode.

A. RCM

Plug the coiled power cord into the Meyer accessory 
port, then into the RCM.
To 

Power On

 the unit - Press and hold the green I/O 

button for 1 second.
(To 

Power Off

 the unit – Press and hold the green I/O 

button for 3 seconds.)

A  screen  will  appear  with  the  MEYER  logo  for 
approximately 3 seconds, after which an operational 
screen  will  appear.    The  operational  screen  will 
show:

 

The E-78 or E-88 icon on the left of the display indicates 
that the PCM is functional and communicating to the 
RCM.  The icon on the right of the display indicates 
that the HCM is functional and communicating to the 
RCM.  If the RCM should lose communication with the 
PCM or HCM for a certain length of time, this icon will 
disappear from the display.

The ALM function is only available when ther PCM and 
HCM are recognized and found in the system by the 
RCM.  When ALM is not available, the button labels 
for them will not be displayed.  The WW button label 
represents the WigWag plow light function.  If there 
isn’t a plow in the system, WigWag is not available and 
the WW button label will not be displayed.

If the RCM does not display the PCM or HCM icon, 
check that the device’s power connector is securely 
plugged in.  When the device is powered on, the RCM 
will automatically detect it and put the appropriate icon 
and button labels on the display.  The RCM searches 
for devices when it is powered on.  Power cycling the 
RCM can  be used to try to find the devices.  There is 
a “FIND DEVICES” item in the Menu that will allow the 
RCM to search for devices.

The LED backlight turns on when the RCM is powered 
on.  It will shut off after 30 seconds. It can be turned 
on again by pressing any button.

NOTE:  If RCM is powered on during the Mounting/
Dismounting sequence, the plow lights will flash and 
the plow will no longer mount/dismount.

UP

” Raise the moldboard by pressing the joystick 

control in the direction of the display. 

DOWN

” Lower the moldboard by pressing the joystick 

control in the opposite direction of the display.  

FLOAT

” if Down is held for .75 seconds, the unit will 

be placed in Float.  While in Float, this icon will appear 
in the middle of the display:   

LEFT

” Angle  moldboard  left  by  pressing  joystick 

control to the left.

RIGHT

” Angle moldboard Right by pressing joystick 

control to the right.

SOFTKEY FEATURES:

ALM

  Press  soft  key  above  ALM  to  activate 

“Automatic  Lower  Mode”,  this  mode  will  cause  the 
moldboard to Lower (place in float) when the vehicle 
is placed in Reverse. Then it will raise the moldboard 
for 2 seconds when taken out of Reverse. (This action 
is only available if backup light wire is connected to 
the HCM)
