F. FAULT CODES
Your monitor comes with built in diagnostic tools. On the controller for stow is a small LED indicator. The primary func-
tion of the LED indicator is to indicate whether the monitor is stowed or deployed. The LED indicator also functions as a
Fault Indicator. Alternately, wire #7 on the J1 harness is an indicator output (2A max.) that will show error & setup codes.
Deployed:
The light will repeatedly flash twice as the unit is deploying. When the fully deployed position is reached
the light will stop flashing and remain on.
NOTE: As soon as the deploy sequence begins, the light in the cab will turn on.
Stowed:
When the fully stowed position is reached the LED indicator will go out.
Fault Code:
1-1 Rotation Sensor (analog or switch)
1-2 Elevation Sensor (analog or switch)
1-7 Rotation Hard Stop (analog feedback units only)
1-8 Elevation Hard Stop (analog feedback units only)
2-1 Electric Riser enabled but not detected

MAINTENANCE INSTRUCTIONS

Your monitor and nozzle should be inspected prior to and after each use to ensure it is in good operating condition.
Periodically, an unanticipated incident occurs where the unit is misused in a manner that is inconsistent with standard
operating practices. A partial list of potential misuses includes:
• Operating above the maximum rated pressure or flow.
• Prolonged exposure to temperatures above 130°F, or below -25°F.
• Operating in a corrosive environment.
• Having the nozzle hit a fixed object during operation or transportation.
• Any other misuse that might be unique to your specific environment.
Also, there are many telltale signs that indicate repair is in order, such as:
• Controls that are either inoperable or difficult to operate.
• Excessive wear
• Poor discharge performance
• Water leaks.
If any of the above situations are encountered, the monitor should be taken out of service, repaired, and tested by a
qualified technician before placing back in service.
MOTOR/GEARING ASSEMBLY REPLACEMENT
To replace either the horizontal or vertical rotational motors, (refer to Exploded View on figure 2):
1 . Disconnect Power from the unit .
2 . Loosen and remove the four socket screws Item (41) from the gearbox housing (19) .
3 . Slowly remove the motor and gearbox housing assembly . To release the worm gear, rotate the discharge waterway with
positive elevation to disengage the worm gear to expel it from the assembly thus removing the motor/gearbox/worm
assembly direction .
4 . Insert new motor and gearbox housing assembly by rotating waterways opposite of step 3 .
5 . Reinsert and tighten four socket screws .
6 . Restore power to the unit .
7 . Test the operation of the unit .
ROTATING JOINT REPLACEMENT
The horizontal or vertical joints are identical in design . It is not necessary to take apart the joint to remove and
replace the motor . To replace the gear sleeve or high density polyethylene (HDPE) bearings, (refer to figure 2):
1 . Disconnect Power from the unit .
2 . Follow steps 2&3 outlined in MOTOR REPLACEMENT .
5
3 . Unbolt the four / hex bolts from the flanges on both sides of the joint casting .
16
4 . Remove travel stops
5 . Slide joint apart, replace worn high density polyethylene bearings (44), bronze gear sleeve (4), o-rings (43 & 45) .
6 . Use proper care to clean old grease residue and liberally apply new grease for re-assembly .
7 . To re-assemble perform steps 2 & 3 in reverse order .
8 . Insert travel stops .
Call Akron Brass Customer Service Department if any problems are encountered .
