Advanced functions
The device 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 6 alphanumerics. Selection of functional readout
in line 3 of the display - choose between readout of analogue output or tag no.
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 via 4501. Then a high signal (not
necessarily 100%) is applied and the actual value is entered via 4501. 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: If you agree to the 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. When you finalise the point with 3, the device
returns to normal mode. The following point allows you to activate relay 1
and relay 2 by means of the arrow-keys up/down. You must exit the menu by
pressing 3 (no time-out).
Password: Here you can choose a password between 0000 and 9999 in order
to protect the device against unauthorised modifications to the configuration.
The device is delivered default without password. If you have locked the
device with a password by mistake, you can always open the menu by using
the master password 2008.
Language: In the menu ”lang.setup” you can choose between 7 different
language versions of help texts that will appear in the menu. You can choose
between UK, DE, FR, IT, ES, SE and DK.
