(2)
Water in oil:
4-20 mA, 0-20 %
0 mA = Water-in-oil sensor not fitted
3.5 mA = Alarm, air in oil chamber
22 mA = Warning, water content far outside the
measuring range
Water in air:
0 mA = Water-in-oil sensor not fitted
3.5 mA, OK
22 mA = Alarm
Analog output 1:
G1 and A1. See fig. 24
(2)
Water in oil:
Pulse output: 0-20 %
Maximum connection: 24 V, 100 mA
Status of output transistor
Pulse A, water in oil:
0.5-3.66 s = 0-20 %
10 s = Water content far outside the measuring
range
Pulse A, water in air:
0.5-3.66 s = OK
10 s = Water content exceeds alarm range
Pulse B, insulation resistance:
0.5 s = 0 MΩ
10.5 s = 20 MΩ
