T- 1.5.0 “TEMP OVER 95 DEGREES” ALARM OCCURRED
A) Install the hydraulics into the cabinet but
DO NOT
screw the rear panels in yet!
B) Place the machine into HEAT DISINFECT.
C) Call debug screen 10. If debug doesn’t appear press ‘Esc’ then call screen 10.
D) Figure right,
5V HI
should NEVER = 5.3 or more;
24V HI
should NEVER =
28.0 or more. If either goes high it may cause “TEMP OVER 95
DEGREES”.
E) Allow thirty (30) minutes OR until if “TEMP OVER 95 DEGREES” reoccurs.
THREE (3) possible scenarios 1) or 2) or 3) below:
1)
IF (and ONLY if) “TEMP OVER 95 DEGREES” DOES NOT reoccur:
The problem is not
occurring at this time. DO NOT continue!
2)
IF (and ONLY if) IF “TEMP OVER 95 DEGREES” reoccurs AND 5V HI = 5.3 or more and / or
24V HI = 28.0 or more:
Proceed to
page 253
, procedure number
3)
IF “TEMP OVER 95 DEGREES” reoccurs BUT 5V HI OR 24V HI DID NOT go high:
This
procedure, parts a THROUGH e below, checks Valve #39. If it opens, as it should, deaeration
pressure will be between 0 and -10 inHg i.e. nowhere near -24 inHg:
a) Turn the machine OFF!
b) The deaeration gauge is used next. ENSURE it
reads 0 inHg before installing it!
c) Figure right, tee the gauge into the Inlet (clear)
tubing of the Deaeratieon Pump.
d)
Place the machine into RINSE (NOT
Heat Disinfect)!
e) Based on the gauge reading, TWO (2) possible
scenarios below:
1)
1) IF (and ONLY if) between 0 and -10 inHg:
Allow the screen’s
[Remaining Time]
window to reach 0:00 BEFORE continuing to procedure number
(page 247)!
2) IF between -11 and -30 inHg:
Read before performing! ENSURING the machine was in
RINSE prior to checking pressure, Valve #39 is not opening!
A)
Turn the machine off;
B)
One at a time, swap in the listed components (COMPONENT LIST below) with known
good then in between;
C)
Return to RINSE;
D)
If the gauge is now between 0 and -10
inHg the last component swapped in is the problem.
COMPONENT LIST: 1)
Actuator-Test Board
2)
Valve #39*;
3)
ACTUATOR cable;
4)
Distribution board.
* To LOCATE Valve #39 refer to the Figure previous page
