5.3 Voltage supply
The supply voltage is connected to terminals "V+
in
" and "V-
in
". Here, it must strictly
observed that the supply voltage lies within the allowable tolerance speci
fi
cations.
Supply voltage: 24 V DC +/- 10 % (400 mA)
Option: Power supply for switch cabinet mounting
Type STEP-PS/1AC/24DC/1.75
Part.-No. 380067
Primary: 1~100...240 V +/- 10 % / 50/60 Hz (600 mA)
Secondary: 24 V DC (1,75 A / 42 W)
for top hat rail mounting
5.4 Digital inputs
The unit has 2-digital inputs:
•
D1
→
Input "Night" (Set Intern2)
•
D2
→
Input "Stop / Start"
Attention!
Never apply line voltage to the digital input!
5.4.1 Digital input "D1" (day- / night switchover)
Day / night changeover for
all
installed
fans takes place via the digital input "D1".
In the unused condition the day value (Set
Intern1) is active. If the connection (D1
with V+
out
) is jumpered, the night speed
set (Set Intern2) is active.
The digital input can be triggered by a
timer, for example. A commercial external
switch could also be connected of course.
