Contacts - switch-off delay
D1of
D2of
D3of
D4of
With this menu, you can define a switch-off delay within a range from 0
to 100 seconds for the selected relay. Set the delay with the arrow keys
and confirm with Enter.
Menu level Aout - analogue output
The settings for the analogue signal output are determined in the menu items.
Analogue output - output signal
outY
This menu defines the output signal range. You can choose between
the following settings: 4-20 mA, 0-20 mA, 20-4 mA and 20-0 mA. Se-
lect by using the arrow keys and confirm with Enter.
Analogue output - minimum measurement value
ZPou
In this menu, you can enter the minimum measurement value which
should correspond to the analogue output signal, e. g. 0 meters. If the
sensor reaches this value, the output will be e. g. 4 mA if the signal
range in menu "outY" was set to 4-20 mA.
Analogue output - maximum measurement value
EPou
Enter the maximum measurement value which has to correspond to
the analogue output signal here. If, for example, "ZPIn" and "EPIn" of a
pressure sensor are given with 0 up to 6 meters, the menu "EPou" can
be set on 5 meters. If the sensor reaches this value, the output will be
e. g. 20 mA if the signal range in menu "outY" was set to 4-20 mA.
Menu level tESt - simulation / testing mode
In this menu level, all test and simulation menus are located. The simulation options cover a
manual relay control as well as an analogue output signal simulation.
Simulation - status of the relays
R1SI
R2SI
R3SI
R4SI
ALSI
This menu is used to simulate the relay conditions. Menu "ALSI" is re-
sponsible for the alarm relay. By using the arrow keys, it is possible to
simulate the "energized" (ON) and "de-energized" (OFF) condition. The
relay will change its condition immediately after selection. Pressing En-
ter will exit the respective simulation menu.
Simulation - status of the analogue output
AnSI
The signal value of the analogue output can be simulated using this
menu. You can pre-set the fixed values 0 mA, 4 mA, 20 mA and varia-
ble values. In order to set a variable signal value, use the arrow keys to
move to screen "SI" meaning output value simulation. Press Enter and
"12.00" mA will appear as simulation value. Now you can set with the
arrow keys the signal value to be rendered on the signal output after
pressing the Enter key. Abort simulation by leaving this menu.
