WORKSHOP MANUAL
The electric installation consists of two accumulator batteries,
an alternator and other control and indicating devices. Op-
eration voltage is 24 V. The minus pole of the accu-batteries is
connected to the machine frame through a disconnecter. The
disconnecter connects or disconnects supplying of the machine
electric system.
In addition to the basic ”car-electricity” of the machine, there are
used electronic elements, some circuits are protected by diodes,
and some instruments include e.g. thyristors.
A hydraulic lock (ATC) is controlled by a control unit (SUSMIK) lo-
cated below the instrument panel. Therefore welding works are
prohibited on the machine, without disconnecting all sensitive
parts from the power supply and/or their dismantling, if possi-
ble, in advance. For example, data inside the SUSMIK equipment
can be erased by welding close to it.
