Slot C = The second option card
An active milliamp signal is connected to A5+ and
A3-. A two-wire transmitter may be connected to
A6+ and A5-. Voltage signal is brought to
terminals A1+ and A3-.
Note that slot A
connectors 3 and 4 must always be linked
together!
If a pre-fuse is used in 230V power supply
connection, it should be at least T500mA. The
indicator has an internal pre-fuse. The polarity of
the power supply has no matter.

Configuration
Using front panel
The indicator can be fully configured using the
front panel keys. The configuration settings are
explained in chapter Settings, and using the front
panel is described in chapter User interface.
The indicator keeps measuring and updating the
alarms, but the serial output is not available.
Using configuration software
MekuWin program (free from Nokeval web site) is
used to configure the device using RS-232 or RS-
485 communication. If connection fails, check the
communications settings using front panel keys to
match those in MekuWin. The settings are
described in chapter Settings / Serial
communications, and the MekuWin program has a
manual of its own.
The Slot parameter in Mekuwin is used to select
which “slot” or card is configured. 0=Master
(setpoint), 1=slot A (input), 2=slot B (output),
3=slot C.
The indicator keeps measuring during the
configuration, and the MekuWin monitor function
can be used to see the current readings.
