Conductive
1+4
1 = measuring electrode
4 = counter electrode
Inductive
1-4
1 = voltage = red
2 = voltage = black
3 = measurement = white / screen
4 = measurement = green
Pt 100
(only for CM)
7,9+10
7 = T1 (Pt 100)
9 = T2 (Pt 100)
10 = RL – for 3-wire connection/cable*
Pt 1000
(only for CM)
8,9+10
8 = T1 (Pt 1000)
9 = T2 (Pt 1000)
10 = RL – for 3-wire connection/cable*
NTC 214k
8-10
8 = T1 (NTC 214k)
9 = T2 (NTC 214k)
9+10 = jumper
Digital input 1
50+51
50 = +, 51 = -, low water, level monitoring,
or controller stop
* For 2-wire-connection there should be a jumper between terminal 9+10
