3 - CONTROL
With these settings, the function of the transistor / relay output terminals is determined.
FUNCTION
31
HIGH ON:
in this case, the control output will be switched-on at the
high level and switched-off at the low level. To be used for
“pump out” applications.
LOW ON:
in this case, the control output will be switched-on at the
low level and switched-off at the high level. To be used for
fill-up applications.
OFF:
to disable the control function. Now the display is a
normal level indicator.
CONTROL VALUE
LOW LEVEL
32
The low level is set with this setting.
CONTROL VALUE
HIGH LEVEL
33
The high level is set with this setting.
DELAY TIME
LOW LEVEL
34
A low ON or OFF generated by SETUP 32 “low” can be ignored during X-
time. If the actual level is still low after this delay time, then the control
output will be switched.
DELAY TIME
HIGH LEVEL
35
A high ON or OFF generated by SETUP 33 “high” can be ignored during
X-time. If the actual level is still high after this delay time, then the control
output will be switched.
4 - DISPLAY
FUNCTION
41
The small 8mm digits can be set to display:
height - percentage - off
EDIT
42
This function determines if the control values can be set at both Operator
level and SETUP-level or SETUP-level only.
If SETUP has been selected, the control values are still visible for the
Operator but can not be changed.
The functions below will only effect the optional LED-backlight.
BACKLIGHT
(OPTION)
43
