A contact on the rear terminal block (terminals 18 and 19) is used
to switch the instrument control from a master device to local mode
or viceversa.
In case of emergency, the operator must regain control on the
instrument by a switch (B) connected in series to the master
control (A) and positioned near the instrument.
The switch should have a minimum rating of 0.5 mA - 12 V DC.
