TROUBLESHOOTING GUIDE
The following chart is intended to assist qualified service personnel with identifying and correcting problems
associated with the electrical/pneumatic systems. The schematic diagrams on the following pages should
be used for reference. A volt–ohm meter will be required.
WARNING
Because these problem solving methods may involve interchanging motor plugs or pneumatic air lines to iso-
late the fault or probable cause, the patient should always be removed from the bed before corrective action
is taken.
PROBLEM/SYMPTOM POSSIBLE CAUSE RECOMMENDED ACTION
No motors functioning. No power supply.
Defective power cord or plug.
Defective electrical controller.
Test voltage at wall receptacle
Examine and test for continuity.

schematic page 7). Listen for relay
actuation.
One motor not functioning –head,
bed, or foot. Loose wire at motor plug or recep- tacle.
Defective motor.
Defective pendant controller.
Defective membrane switch.
Defective electrical controller (circuit
board).
Inspect connectors; check continuity.
Interchange motor plugs to isolate.
Interchange motor plugs to isolate.
Check continuity.
Test input and output voltages (see
schematic page 7). Listen for relay
actuation.
Incorrect travel limits –head, bed or
foot. Physical blockage of movement. Defective motor or drive screw.
Motor drive tube out of adjustment.
Visually inspect moving parts.
Replace motor (see pages 9–11).
Reset (see motor replacement–
pages 9–11)
One pneumatic solenoid not func-
tioning –lumbar, seat left or seat
right.
Loose wire at solenoid plug.
Defective solenoid.
Defective pendant controller.
Defective membrane switch.
Defective electrical controller (circuit
board).
Inspect connectors; check continuity.
Interchange solenoid plugs to iso-
late. Replace coil.
Interchange solenoid plugs to iso-
late.
Check continuity.
Test input and output voltages (see
schematic page 7).
No inflation of lumbar, seat left, or
seat right. Leaking bladder. Replace head panel–mattress or seat panel–mattress (see page 15 or
16).
No inflation or deflation of lumbar,
seat left, or seat right. Kinked lines.
Defective solenoid.
Inspect lines for kinking: re–route, if
necessary.
Interchange solenoid plugs to iso-
late.
No air to operate lumbar, seat left, or
seat right. Defective compressor. Loose wire at motor connectors. Replace compressor (see page 14). Inspect connectors: check continuity;
test voltage.
Slow filling or emptying of air from
lumbar, seat left, or seat right. Kinked lines.
Contamination in valves.
Inspect lines for kinking: re–route, if
necessary.
Isolate by switching lines. Replace
manifold (see page 17).
Squeal or noise in lift mechanism Or,
bed motor labors when bed is fully
loaded with 300 pounds.
Dry joints.
Defective counterbalance spring. See prev. maintenance (page 4). Check for obstruction, bent rod, or
bent housing. Remove obstruction.
Replace spring (see page 20).

TROUBLESHOOTING GUIDE (CONTINUED)
PROBLEM/SYMPTOM POSSIBLE CAUSE RECOMMENDED ACTION
Bed does not tilt when lever is de-
pressed. Tilt spring out of adjustment. Defective tilt spring. Readjust spring length. Replace spring (see page 21).
Bed tilts when weight is applied to
opposite ends. Tilt spring out of adjustment. Defective tilt spring. Readjust spring length. Replace spring (see page 21).
Brakes do not lock wheels. Tire wear. Readjust casters
Brakes hard to apply. Brakes over–adjusted. Readjust casters
NURSE COMMUNICATION SIDERAIL OPTION TROUBLESHOOTING GUIDE
Before attempting to diagnose an apparent problem, be sure the power cord is plugged into a properly
grounded hospital grade wall receptacle and the bed has power. Be sure the nurse call cable has a good
connection at both the wall and the bed. If both these things are done, proceed with diagnosis.
CAUTION
Membrane switches are fragile. Never depress a membrane dome unless the switch is lying on a flat, firm
surface. Doing otherwise will cause the switch to fail eventually. When applying a new membrane switch,
lay it down evenly; do not roll it down. Once a membrane switch has been peeled back, it cannot be reused.
PROBLEM/SYMPTOM POSSIBLE CAUSE RECOMMENDED ACTION
Some or all of the pillow speaker
functions aren’t working properly. Defective cable (from bed to wall). Switch the cable with one that is known to work. If this solves the
problem, replace the cable. If not, try
a bed from another room that is
known to be O.K. If the problem per-
sists on the bed that is known be
O.K., the problem is in the wiring in
the wall.
A control button on one side of the
siderail doesn’t work or the T.V.
sounds different on one side.*
Defective control switch.
Defective siderail P.C. board.
Defective splitter box.***
Defective siderail cable.
Replace switch.**
Replace siderail PC board.**
Switch the siderail cables at the split-
ter box. If the problem switches
sides, replace splitter box. If the
problem stays in the same siderail,
replace cable.
* For audio problems, check resistance across pins 4 and 35 on the 37 pin connector at the rear of the bed.
The reading should be 22.5 "5 ohms for 45 ohm systems or 4 "2 ohms for 8 ohm systems. A reading
double these values indicates no connection to the speaker in one of the siderails. If the sound is inade-
quate, turn the volume up to its highest level by holding the button for 30 seconds. Adjust the remote speak-
er output volume on the TV to its highest level. Turn the TV back down until the volume at the remote speak-
ers just begins to be affected to reduce distortion caused by overdriving the speakers. Cover the speaker
grills separately and compare the sound loss to be sure the sound is balanced between the two speakers.
** For problems inside the siderails, peel back the outside membrane switch to expose the seven screws hold-
ing the plastic housing to the siderail assembly. Remove the screws and carefully disconnect the mem-
brane switch from the siderail PC board.
*** For problems in the splitter box, remove the box and examine the LED’s next to the relays. If the LED comes
on when the function button is pressed, a faint click should be audible. If no click is heard, replace the relay.
If replacing the relay doesn’t solve the problem or if the LED doesn’t light, replace the splitter box PC board.
If the problem still persists, replace the splitter cable. (Refer to Splitter Box Assembly (page 49) for part
reference.)
