As defined by standard IEC 1131-2.
(2)
RET not used on 2-wire devices.
(3)
Add external resistor from 24V to F or G for wire-off detection (0.4 mA) – (
≈
50 K
Ω
).
(4)
Add a jumper between 50 mV and RET (Frequency – channel 0 = 3…4; channel 1 = 11…12)
(Gate – channel 0 = 21…20; channel 1 = 28…29).
(5)
Connect cable shields to GND terminals.
(6)
24V terminal may not be used on 2-wire magnetic devices.
(7)
All 4 RET terminals (ch 0 and 1, Freq, Gate) are internally connected together.
ATTENTION
Total current draw through the terminal base unit is limited to 10 A.
Separate power connections to the terminal base unit may be
necessary.
