Menu level rELn - parameter of the contacts (relais)
The menu items of this level are responsible for the limit value settings and the switching behav-
iour of the relays. Since the menus for the relays have been conceived identically, the descrip-
tion is the same for all menus. This menu level can be called up by pressing Enter like any other
menu. After that, the respective relay must be selected. This can be achieved by selecting the
numbers of the relay with the arrow keys. Confirm your selection with Enter (standard: 2 relays /
option: 4 relays).
Contacts - switching mode hysteresis/compare
HY 1 / CP 1
HY 2 / CP 2
HY 3 / CP 3
HY 4 / CP 4
With this menu, you can define the switching logic of the relays. It is pos-
sible to select between the so-called hysteresis mode HY X (limit level)
and the compare mode CP X (in bounds/out of bounds). Select with ar-
row keys as usual – HYon indicates the selected hysteresis mode (limit
level). CPon will indicate the window mode (in bounds/out of bounds).
Confirm with Enter. (compare 7. Programming examples)
Contacts - switching point
S1on
S2on
S3on
S4on
This menu defines the upper switching point of the respective relay. The
programming example shows the function of this menu. In hysteresis
mode (limit level), this value determines e. g. the turn-on point. In window
mode (in bounds/out of bounds), this value determines e. g. the in
bounds upper switching point. The value can be set using the arrow keys.
Confirm with Enter.
Contacts - reset point
S1of
S2of
S3of
S4of
This menu defines the lower switching point of the respective relay. The
programming example shows the function of this menu. In hysteresis
mode (limit level), this value determines e. g. the reset point. In compare
mode (in bounds/out of bounds), this value determines e. g. the in
bounds lower switching point. The value can be set using the arrow keys.
Confirm with Enter.
Contacts - inverting
In 1
In 2
In 3
In 4
This menu allows you to invert the relay position. In hysteresis mode
(limit level), the upper and lower switching points will be changed. In
window mode (in bounds/out of bounds), the switching behaviour will
change from in bounds to out of bounds. Please note that this determina-
tion is valid only in case of activated auxiliary power, as the relay has to
be powered with auxiliary power depending on the parameter setting.
Relay inversion will be set by using the arrow keys. "St" in the display
indicates the standard position, "In" the inverted relay position. Confirm
the setting with Enter.
Contacts - switch-on delay
D1on
D2on
D3on
D4on
This menu is used to define a switch-on delay within a range from 0 to
100 seconds for the selected relay. Set the delay with the arrow keys
and confirm with Enter.
