Troubleshooting / Problem Solving
Problem description:
While pressing the ‘Chassis legs open’ button, the Tenor makes a noise, “overload” dis-
plays on the LCD and the buzzer beeps continuously but the chassis legs are not open-
ing.
Probable cause:
An obstruction is blocking the chassis legs.
Solution:
Please remove the obstruction and check thoroughly for damage before continuing the
lifting cycle. When in doubt, use the System Failure Lowering Override to put the resident
back into a safe seated position before removing the Tenor and placing it out of order till
it has been inspected and approved for safe working by an Arjo approved engineer.
Problem description:
The functions on the Tenor are not working properly
Probable cause:
Malfunction of EMC of the hoist making the hoist vulnerable for radiation influences of
other machinery
Solution
Operate the Tenor in an environment without influence of radiation.
Problem description:
Unexpected movement of the hoist
Probable cause:
Two control buttons pressed simultaneously; faulty hand control, push buttons or elec-
tronics
Solution
Release both control buttons. If this doesn’t work, press the red Emergency Stop button
and remove the battery. Use the System Failure Lowering Override to put the resident
back into a safe seated position before removing the Tenor and placing it out of order till
it has been inspected and approved for safe working by an Arjo approved engineer.
Problem description:
“OverHeat” displays and the buzzer beeps twice every 15s.
Probable cause:
Operator excess the actuator duty cycle (2 min ON and 18 min OFF)
Solution

age.
