Solution |
| Table will not operate when any of the eight up or down functions are selected. |
When a foot pedal is depressed, motor pump does not run and solenoid cannot be heard being energized (audible click) |
Power cord is not plugged into facility wall outlet or, on export models, power cord isn't plugged into connector receptacle on table |
Check to see if power cord is plugged in |
Plug power cord into facility wall outlet and/or connector receptacle on table |
|
|
Facility circuit breaker providing power to table is tripped. |
Check to see if facility circuit breaker is tripped. One way of checking this is to plug a lamp into wall outlet that table was plugged into |
If circuit breaker is tripped, determine what caused circuit breaker to trip, correct the problem, and then reset/replace circuit breaker |
|
|
Fuse(s) in AC connector receptacle is blown (export units only) |
Perform continuity check on fuses |
Replace fuse(s) |
|
|
Wire connections loose |
Check all wiring connections from power cord to terminal block and from foot control to terminal block. Perform continuity check on wires. Use multimeter to check for proper voltage levels |
Clean any dirty connections. Tighten any loose connections. Replace any damaged connections |
|
|
Isolation transformer is malfunctioning (export units only) |
Check input and output voltage of isolation transformer or replace suspect isolation transformer with known working transformer |
If isolation transformer is receiving proper input voltage but is not supplying 115 VAC output, replace isolation transformer |
|
When a foot pedal is depressed, motor pump does not run, but solenoid can be heard being energized (audible click) |
Capacitor(s) is blown (motor pump may be humming |
Replace suspect capacitor(s) with known working capacitor(s) |
Replace capacitor(s) Part #MIC120-6313 |
|
|
Motor thermal overload switch is activated because motor pump overheated |
Unplug power cord and then wait 15 to 20 minutes |
Allow motor pump to cool and then try to operate table. If motor pump does not run now, replace motor pump |
|
|
Motor pump is burned out |
Replace suspect motor pump with known working motor pump |
Replace motor pump |
|
|
Wire connections loose |
Check all wiring connections from terminal block to motor pump. Use multimeter to check for proper voltage levels |
Clean any dirty connections. Tighten any loose connections. Replace any damaged connections |
|
When a foot pedal is depressed, motor pump runs, but table top does not move |
Time delay relay is malfunctioning |
Use a jumper wire to bypass time delay relay. If table moves, time delay relay is malfunctioning.
Put a multimeter in line w/time delay relay and run each cylinder one at a time |
A multimeter reading > 1.2 amps indicates a malfunctioning cylinder has caused the relay to fail.
Replace the malfunctioning cylinder and the time delay relay. Refer to proper cylinder replacement instructions.
If reading is < 1.2 amps, replace time delay relay only |
|
When a foot pedal is depressed, motor pump runs and solenoid can be heard energizing |
Hydraulic system is low on mineral oil |
Check oil level in reservoir |
If necessary, add oil to reservoir Part #RPF384-6316 |
|
When a foot pedal is depressed, motor pump hums, but does not run |
Capacitor(s) is blown |
Replace suspect capacitor(s) with known working capacitor(s) |
Replace capacitor(s) Part #MIC020-6313 |
|
|
Motor pump is locked up or burned out |
Replace suspect motor pump with known working motor pump |
Replace motor pump |
