10.3 Connection of up to four switching outputs
Connection example for four switching outputs, e. g. HDA 5500-1-2-AC-000, is shown below.
Depending on the auxiliary voltage and load (especially for inductive loads) the external
circuit must be fitted with a varistor.
11 Adjusting switching outputs
Procedure for HDA 5500 with switching outputs:
•
During normal operation, press mode key.
•
Depending on the settings SP (switch points) or Win (switching window) will be displayed
(if no switching outputs are available, noSP (no switch point) will be displayed).
•
After approximately 2 s the display returns to normal operation.
Note:
If the mode key is pressed for longer than approximately 5 s, then the Basic Settings Menu
will be activated!
11.1 Switch points and hysteresis
Procedure for HDA 5500 with two or four switching outputs (with switching output set to
switch point and hysteresis mode):
•
During normal operation, press the mode key. SP (switch point) is then displayed.
Note: If the mode key is pressed for longer than approximately 5 s, then the Basic Set-
tings Menu will be activated!
•
As soon as the mode key is released, S.P.1 (switch point 1) is displayed.
•
After approx. 2 s the display changes and the pre-set switch point flashes in the display.
•
If the mode key is pressed again, hYS.1 (hysteresis 1) appears in the display.
•
By pressing the mode key once more on the HDA 5500 with two switching outputs S.P.2
(switch point 2) and hYS.2 (hysteresis 2) are shown one after the other in the display and
on the HDA 5500 with four switching outputs S.P.3 (switch point 3), hYS.3 (hysteresis 3),
S.P.4 (switch point 4) and hYS.4 (hysteresis 1) are also shown.
•
If a switch point or hysteresis is shown flashing, the setting can be changed by pressing
or
within approximately 3 s.
•
If
or
is not pressed for approximately 3 s or longer, then the display returns to
normal operation. Any altered settings are saved at the same time.
