Instructions for use - BW 585
BIEGLER
6 PERIODIC INSPECTIONS
Periodic technical safety inspections must be performed on the BW 585 at least
every 12 months by persons who on the basis of their training, knowledge and
practical experience are qualified to carry out such technical safety testing.
The results of the periodic inspection are to be entered, together with the date
and the inspecting agency, on the reverse side of the instructions for use.
Important: If a malfunction is identified in the periodic inspection, affix a suitable
warning notice on the device to ensure that it can no longer be used until the
necessary repairs have been carried out.
CHECKING THE WARM-UP PERIOD
This is the time taken by the BW 585 to heat up to 41.0°C from room
temperature. The device is malfunctioning if it takes much longer than one
minute.
CHECKING THE CONTROL TEMPERATURE
The control temperature is checked on the groove bed of the heat exchanger.
The sensor of a suitable contact thermometer (tol/- 0.15°C) is fixed to
this place e.g. using a piece of infusion tubing. The check is performed at a
temperature setting of 38.5°C. The measured value is read after it has
stabilized. The difference must not /- 0.5°C. There is a malfunction if a
difference from control temperature of greater than +/- 0.5°C is obtained.
CHECKING THE LOW TEMPERATURE ALARM
Preheat the device to 38.5°C, then disconnect the mains plug. Hold down the
control
and reconnect the mains plug. Push the
switch. The device is now
in an operational state where all the alarms are active, but the heating is
switched off. The BW 585 now slowly cools down. When the temperature drops
below the 36.5°C threshold, the low temperature alarm should be active.
For reasons of safety, short beeping sounds are given at intervals of a second in
this operational mode and the LED ON and STANDBY indicators flash
alternately (Diag.1/4 and Diag.1/5). There is a malfunction if the low temperature
alarm is not triggered.

CHECKING THE HIGH TEMPERATURE ALARM
Preheat the device to 41°C and wait for the temperature to stabilize, then
disconnect the mains plug. Hold down the control
and reconnect the mains
power plug. Push the
switch. The device now heats up to a target
temperature of 42.5°C. Observe the temperature indicator carefully. The high
temperature alarm should be triggered at a temperature of 42°C.
For reasons of safety, short beeping sounds are given at intervals of a second in
this operational mode and the LED ON and STANDBY indicators flash
alternately (Diag.1/4 and Diag.1/5). There is a malfunction if the high
temperature alarm is not triggered.
VISUAL CHECK OF GENERAL CONDITION AND STICKERS
The device should be checked for mechanical damage (general condition) and
for the completeness of sticker information, particularly the plate on the reverse.
There is a malfunction if mechanical damage to the device is evident which
could be harmful or impair the functional operation of the device.
ELECTRICAL SAFETY
All relevant electrical safety data should be checked, particularly the earth
conductor resistance (< 0.3 Ohm) and leakage current (< 0.75 mA). There is a
malfunction if there is a value outside the tolerances.
