signal and sensor error information via display front 4501
Sensor error (see limits in the table) is displayed as SE.BR (sensor break) or SE.SH
(sensor short). Signals outside the selected range (not sensor error, see table
for limits) are displayed as IN.LO indicating low input signal or IN.HI indicating
high input signal. The error indication is displayed as text in line 2 for channel
1 and line 3 for channel 2 and at the same time the backlight flashes. Line 4
of the display is a status line which shows whether the device is SIL-locked
(static dot = SIL-locked and flashing dot = not SIL-locked) as well as status for
communication COM (running circle) indicating correct functioning of 4501.
signal and sensor error indication without display front
Status of the unit can also be read from the 3 LEDs in the front of the device.
Green flashing LED indicates normal operation.
No light in the green LED indicates lack of supply voltage or error in the device.
Steady red LED indicates fatal error.
Flashing red LED indicates sensor error.
Advanced functions
The unit gives access to a number of advanced functions which can be reached
by answering "YES" to the point "ADV.SET".
Display setup: Here you can adjust the brightness contrast and the backlight.
Setup of TAG numbers with 5 alphanumerics. Selection of functional readout
in line 2 and 3 of the display - choose between readout of analogue input,
analogue output or tag no or alternating display.
Two-point process calibration: The device can be process-calibrated in 2 points
to fit a given input signal . A low input signal (not necessarily 0%) is applied
and the actual value is entered. Then a high signal (not necessarily 100%) is
applied and the actual value is entered. If you accept to use the calibration, the
device will work according to this new adjustment. If you later reject this menu
point or choose another type of input signal the device will return to factory
calibration.
process simulation function: In the menu point "EN.SIM" it is possible to
simulate an input signal by means of the arrow keys and thus control the
output signal up or down. You must exit the menu by pressing 3 (no time-out).
The simulation function exits automatically, if the 4501 is detached.
