16 USER MANUAL ME-01
Outputs are adapted for direct connection RM96P transmitter of DC24V input
voltage and AC250V 8A output. Transmitter’s coil has to be secured with diode
e.g. 1N4148.
It is recommended to use MS 3K/P electronic board (3 transmitters of RM96P
type – max. load of 3A/250V) or complete ST 3K/P control box (feeder, 3
transmitters like above).
The way THRESHOLD outputs work is described in the separate document
(Special functions description).
9.2 External key connection
The input of external keys allows to place (make double) selected scale keys into
control box or operator’s workstation. As a standard the input is taken out with a
wire for direct connect to a control panel. ME-01 indicators can be equipped with
external key interfaces (as an option on demand).
Marker numbers and outer wires colors indicators:

External key connecting is shown below. It is crucial to use external supply (24V)
in order to make current flow through scale transoptor input. This way of
connection provides galvanic separation of the scale from automatics system
which increases resistance to external interference and increases reliability.
