P- H.1.3 ISOLATE HYDRAULIC SENSORS
a) To prevent damage turn the machine OFF!
b) CAREFULLY* return the module cables to their positions.
* CAUTION! DO NOT a plug a module, other than the Blood Pressure Module, into the Blood
Pressure or Colin position! DO NOT plug the Blood Pressure Module into another module’s
position! NEVER plug the Bood Pressure module in with the machine on!
c) CAREFUL HERE!
Per the Figure below, unplug the SENSOR cable from the Distribution board!
d) Repeat the Voltage Detection Calibration. THREE (3) possible scenarios 1) or 2) or 3):
1) IF (and ONLY if) “Operator Error” reoccurs: See procedure number P- H.1.4 (page 677).
2) IF (and ONLY if) 5V EST AND / OR 12V EST are not in range: See procedure number P- H.1.4
(page 677).
3) IF “Operator Error” did NOT occur AND 5V EST AND 12V EST are in range: One of (12)
twelve Sensors or one of five (5) Pumps may be causing the problem! Perform parts A THROUGH
C below to locate which one:
A)
IMPORTANT! Turn the machine OFF and reconnect the Sensor Board cable.
B) Per the Figure above, your choice, unplug ONE of thirteen (13) hydraulic Sensors or ONE of
five (5) Pumps from the Distribution board.
C) Attempt the Voltage Detection Calibration. TWO (2) possible scenarios:
1) IF “Operator Error” does NOT occur AND 5V EST AND 12V EST are in range: The
last component unplugged may be causing the problem.
2) IF “Operator Error” occurs OR 5V EST OR 12V EST are NOT in range: Repeat parts B
through C until ALL thirteen (13) sensors (NTC #2 through NTC #44 AND the Blood Leak
Sensor) AND ALL five (5) pumps (#16 through #22), have been unplugged.
NOTE! AFTER all components have been unplugged AND the problem reoccurs swap the
Sensor Board cable with a known good. If (and ONLY if) the problem reoccurs see
procedure number P- H.1.4 (page 677).
