Control System 34 Service Manual – SC1500
Detergent (EcoFlex
™ ) Option
The
5. ECOFLEX INSTALLED
submenus allow you to enable or disable the
detergent system.
• If the menu setting is
YES
, the controller will expect a Detergent
Pump to be installed. If no Detergent Pump is installed, eventually the
Control Board could generate an error code.
• If the menu setting is
NO
, the Detergent Strength Switch has no
effect on machine operation, and the graphic display will not show
the Detergent Indicator Bar Graph. Note that if the machine has a
detergent system installed, it will not work when the menu setting
NO
is selected.
The default setting is
NO
Chemical Rate Bias
The
6. CHEMICAL RATE BIAS
submenus allow you to increase or decrease
the detergent/chemical mix rate by 10 percent to achieve a higher or
lower mix concentration than the selected programmed ratio.
• The
-10% LESS CHEMICAL
setting will increase
the wait time
between Detergent Pump delivery pulses 10 percent to decrease
detergent flow.
• The
+10% MORE CHEMICAL
setting will decrease
the wait time
between Detergent Pump delivery pulses 10 percent to increase
detergent flow.
Note that the
6. CHEMICAL RATE BIAS
submenus only have an effect if the
ECOFLEX INSTALLED / YES
option is selected (see above).
The default setting is
NONE
Open Fault Detect
Normally, the A1 Control Board will perform checks of the electrical
system during operation. If a fault occurs in a particular system,
that system (and possibly others) will be shut down. This can make
troubleshooting the system difficult. The
7. OPEN FAULT DETECT
submenus allow service personnel to disable all of the open circuit faults
to facilitate troubleshooting. Note that selecting
OPEN FAULT DETECT /
OFF
will not disable the over-current protection on any of the systems.
The default setting is
OFF
Display Rev Level
The
8. DISPLAY REV LEVEL
submenu displays the revision level of the
software in the A1 Control Board. This revision level is a parameter hard-
coded in the software.
