Fresenius Medical Care 4008 4/08.03 (TM) 5-3
5.1 General notes
The diagnostics program serves to activate all inputs and outputs of the hemodialysis machine.
Activation is related to CPU1 (P.C.B. LP 631), CPU2 (P.C.B. LP 632), as well as to the output
board (P.C.B. LP 634) and the input board (P.C.B. LP 633).
Using this program, the technician is able to program his own settings for testing of error images.
The diagnostics program is divided into the following menus:
– READ INPUTS
– READ ANALOG INPUTS
– CPU1: RD ANALOG INP.
– CPU2: RD ANALOG INP.
– READ DIGITAL INPUTS
– CPU1: RD DIGITAL INP
– CPU2: RD DIGITAL INP
– WRITE OUTPUTS
– WRITE ANALOG OUTPUTS
– CPU1: WR ANALOG OUTP
– CPU2: WR ANALOG OUTP
– WRITE DIGIT. OUTPUTS
– CPU1: WR DIGIT. OUTP
– CPU2: WR DIGIT. OUTP
– INP/OUTP COMBINATION
– CPU1: COMBINATION
– CAN–COMPONENTS
– WTR
– ONLINE–PLUS–MODUL
In order to indicate the corresponding levels, all UF-seven-segment displays as well as the status
indicator (monitor), the external traffic light and the loudspeaker are used in the “READ DIGITAL
INPUTS” menu.
The active signal state (which may correspond to both present and absent voltage) is indicated by
1111 on the UF displays, activated traffic light (status indicator) and audible signal.
An audible signal can be deactivated by pressing the (Alarm) Tone Mute key. With the audible
signal deactivated, the (Alarm) Tone Mute LED is flashing as a reminder.
The audible signal indication can be used to evaluate the state of the signal without having to look
at the monitor. This may be advantageous in case measurements have to be made behind the
machine (e.g. hydraulic unit).
