IS THE “ HEALTH” LED FLASHING GREEN, ONCE PER SECOND?
NO:
IF THE HEALTH LED IS OUT OR IS LIT STEADY, THE M AIN

#4 LED
ARE THE TX/ RX LEDs FLASHING ON REM OTE 10 TIM ESPER
SECOND?
NO, TRY ASSOCIATING A KNOWN-GOOD REM OTE TO THE
RECEIVER.
IF NEW REM OTE WILL NOT ASSOCIATE TO THE
RECEIVER, RET U RN T H E RECEI V ER FOR
SERV I CE

THIS GUIDE APPLIES TO 302 & 5 SERIES M ACHINES
IF NO PART OF THE M ACHINE CAN BE CONTROLLED:
CHECK SUPPLY VOLTAGE:
IS SUPPLY VOLTAGE OVER 28 VOLTS? (NOTE: VERY FAST “ SPIKES” COUNT—
M AY NOT BE DETECTIBLE ON M OST DIGITAL VOLT M ETERS)
YES: THE RECEIVER IS FAULTING ON AN OVER-VOLTAGE CONDITION;
REQUIRES POWER CYCLE (TURN OFF, TURN ON) TO REGAIN
CONTROL. INSPECT POWER SUPPLY (BATTERY, BATTERY LUGS,
ALTERNATOR, WIRING) AND CORRECT ANY ISSUES
NO: CONTINUE TO NEXT STEP

THIS GUIDE APPLIES TO 302 & 5 SERIES M ACHINES
IF NO PART OF THE M ACHINE CAN BE CONTROLLED:
CHECK SUPPLY VOLTAGE:
IS THE SUPPLY VOLTAGE UNDER 7 VOLTS?
YES: THE RECEIVER IS STARVING FOR POWER. LOAD TEST THE
BATTERY AND CHECK THE POWER SUPPLY WIRING.
NO: CHECK WIRING TO ENSURE THAT ALL HYDRAULIC VALVE COIL
RETURNS AND ANY OTHER OUTPUT LOAD RETURNS ARE TIED TO
THE SAM E POINT AND THAT POINT ISTIED TO BATTERY
NEGATIVE AND THE “ -VDC” (GROUND) PIN ON THE RECEIVER.

POSSIBLE OPEN-CIRCUIT ON ONE OR M ORE OUTPUT CHANNELS
CHECK WIRING FOR BROKEN CONNECTIONS
CHECK HYDRAULIC VALVE COILS FOR CONTINUITY (TYPICAL VALVE COIL RESISTANCE IS25 OHM S OR LESS)
SWAP CONNECTORS FROM SUSPECTED BAD VALVE TO ONE THAT IS KNOWN TO
WORK
DOES SUSPECTED OUTPUT CHANNEL OPERATE THE “ NEW” FUNCTION?

NO:
OBSTRUCTIONS ARE LIM ITING THE RADIO RANGE.
REPOSITION THE OPERATOR OR THE M ACHINE TO M AINTAIN LINE-OF-SIGHT CONDITIONS AS M UCH AS
POSSIBLE.
YES:
LARGE M ETAL OBJECTS NEAR THE M ACHINE OR OPERATOR M AY BE REFLECTING RADIO ENERGY FROM THE
REM OTE CONTROL SYSTEM IN SUCH A WAY THAT THE REFLECTIONS ARE INTERFERING WITH THE LINE-OF-
SIGHT SIGNAL.
OR
ANOTHER RADIO SIGNAL IS INTERFERING WITH THE REM OTE CONTROL’S RADIO SIGNAL; DISASSOCIATE AND
REASSOCIATE REM OTE AND RECEIVER. THIS ALLOWS THE REM OTE TO SCAN THE RADIO CHANNELS THAT IT
CAN OPERATE ON AND DETERM INE THE BEST CHANNEL TO WORK WITH. IF THERE IS AN INTERFERING
SIGNAL IT M AY TAKE SEVERAL ATTEM PTS TO BE SYNCHED.
DAM AGE TO THE REM OTE OR ANTENNA CAN ALSO REDUCE THE RANGE OF THE SYTEM .
IS THE RADIO CONTROL SYSTEM OPERATING UNDER LINE-OF-SIGHT CONDITIONS?

ALL REPLACEM ENT REM OTES M UST BE ASSOCIATED TO THE RECEIVER BEFORE THE REM OTE CAN OPERATE THE M ACHINE.
EVERY REM OTE AND RECEIVER HAVE A UNIQUE ID CODE WHICH M UST BE EXCHANGED.
IF A REM OTE WASREPLACED BECAUSE IT IS SUSPECTED AS THE CAUSE OF A M ALFUNCTION WITH THE SYSTEM , THE
RECEIVER M AY BE THE CULPRIT INSTEAD.
CHECK THE “ WSNUM BER” OF THE REM OTE AND RECEIVER. THE WS NUM BER DETERM INES THE PROJECT SPECIFICATIONS
UNDER WHICH EACH PIECE OF A CERVIS, INC. RADIO SYSTEM ISCONFIGURED. IF THE WS NUM BER DOES NOT M ATCH
BETWEEN A RECEIVER AND REM OTE, THEY ARE LIKELY INCOM PATIBLE.
M ANY PIECES FROM DIFFERENT SYSTEM S LOOK IDENTICAL TO EACH OTHER BUT ARE NOT CONFIGURED THE SAM E.
THE WSNUM BER CAN BE FOUND ON THE FACEPLATE LABEL OF THE RECEIVER AND INSIDE THE BATTERY COM PARTM ENT OF
THE REM OTE .
EVEN IF THE REM OTE WILL ASSOCIATE TO THE RECEIVER, THERE M AY BE A M ISM ATCH IN FUNCTIONALITY
IT IS POSSIBLE THAT NOT ALL FUNCTIONSWILL OPERATE OR THAT SWITCHES AND CONTROLS WILL NOT OPERATE THE
FUNCTION THAT ISEXPECTED BUT WILL OPERATE A DIFFERENT FUNCTION WHICH COULD POSE A DANGEROUSSITUATION.
