+U
s
✓ ✓ ✓ ✓ Regulator supply voltage (positive pole)
• DS7-340…:
+24 V DC, +10 %/-15 %, 150 mA
24 V AC, +10 %/-15 %, 150 mA, 50/60 Hz
• DS7-342…:
120 - 230 V AC, +10 %/-15 %, 100 mA at 230 V, 50/60 Hz
-U
s
✓ ✓ ✓ Reference potential (O V) for +U
s
+A1 ✓ ✓ ✓ ✓ Control input start/stop (positive pole)
Same voltage level as +U
s
Low level: 0 - 3 V;
High level: 4.6 – +U
s
Current drain:
DS7-340…: 1.6 mA at 24 V
DS7-342…: 4 mA at 230 V
-A2 ✓ ✓ ✓ ✓ Reference potential (O V) per +A1
In the case of size 1, reference potential for relay contact 13 (TOR) and +U
s
as well
EN ✓ ✓ Control input, controller enable (enable, positive pole)
EN must be actuated A1.
If the t-Stop function is used, EN should not be disconnected until after the RUN signal has been
deactivated.
If EN is deactivated in RUN mode, the drive will execute an uncontrolled stop.
13 ( ✓ ) ✓ ✓ ✓ Relay contact, N/O TOR (Top-of-Ramp)
230 V AC, 1 A, AC 11
Notice!
In the case of size 1, the type (AC/DC) and magnitude (24 V/230 V) of the voltage being switched
(TOR: 13/-A2) must be identical to those of the control voltage: +U
s
= +A1 = 13, reference potential -A2
14 ✓ ✓ ✓ Common contact of TOR relay contact (control signal terminal 13)
23 ✓ ✓ ✓ Relay contact, N/O RUN (RUN signal) / READY
230 V AC, 1 A, AC 11
24 ✓ ✓ ✓ Common contact of RUN / READY (control signal terminal 23)
