CHAPTER 4
TESTING
The following serviceability tests should be performed before returning the bed to use after service, or if
any function is suspect.
These instructions should be read in conjunction with the instructions for use supplied with the product
(part number 746-585).
If the result of any test is unsatisfactory, investigate and take the appropriate remedial action. Refer to
Chapter 5, Troubleshooting and Chapter 6, Servicing Instructions.
All references to left or right of the bed are when viewed from the head end (i.e. by a patient lying on the
bed).
1 Preliminary
Do the following preliminary checks before testing:
• Verify that no furniture or other obstruction can impede the movements of the bed.
• Connect the bed to the power supply. If necessary, reinstate all locked out functions.
2 Electrical Functions
The following tests check the electrical functions:
2.1 Bed Controls
To check the bed controls:
2.1.1 Check that each ACP operates all bed functions (height, backrest angle, leg elevation, tilt and
Auto-Chair). Verify satisfactory operation over the full range of movement as specified in Chapter
7, Technical Data. Verify that the actuators are de-energised when the control button is released
or the limit of travel is reached.
2.1.2 Check that both sets of patient controls operate the backrest, leg elevation and Bio-Contour
functions.
2.1.3 Check that both sets of nurse controls operate the backrest, leg elevation and height functions.
2.1.4 Verify that the lockout function on the ACP disables the appropriate functions on all of the control
units.
2.1.5 Raise the backrest and leg sections and raise the mattress platform to top height. Press and hold
the CPR button and verify that the mattress platform returns to a flat, mid height condition.
2.1.6 Check the function of the underbed lights. The underbed lights are illuminated whenever the bed
is connected to the mains supply.
WARNING
If any electrical assembly or wiring has been replaced or repaired, the
appropriate electrical safety checks must be made.
Keep clear of the bed when it is being operated. Severe injury can result from
crushing by moving parts.
