Base
Mounting on electromechanical plate with quick
coupling to DIN EN50022 guide or with 5mA
screws
Base with "Double Relay” module
7) Attach the protective cover of the power terminals and
connect the wire to the ground terminal.
8) If the module is a Master (GFX-M2...), wire its connector to
the serial interface see "Electrical Connections").
9) If the module is a Slave (GFX-S2...) or Expansion (GFX-
E2...), attach the flat wire to the corresponding connector "J3"
of the module immediately to the left (see "Connection
Examples").
Led L2 "Error" LED (red)
Activates when one of the following errors is present:
LO = process variable value is < di Lo.S
HI = process variable value is > di Hi.S
Sbr = broken probe or input values beyond maximum
limits
Err = third wire broken for Pt100, PTC or input values
below minimum limits
(ex.: for CT with incorrect connection)
