PMR-Nano
Intended use
ARIS microprocessor controllers, series PMR-Nano, are used for activating ARIS actuators. They are integrated in the actuator hous-
ing. PMR-Nano series microprocessor controllers position the actuator based on a reference input (set point). The PMR controller com-
pares the preset set point with the current position of the actuator (actual value). In case the values differ from each other, the actu-
ator is moved to the position specified by the set point. The actual value is determined by a potentiometer, integrated in the actuator.
Electrical connection
Protective measures shall be implemented in accordance with VDE (Association of German Electrotechnical Engineers) and EVU
(Electricity Board) regulations. In particular, VDE Regulation 0105 “Working on Live Components” shall be followed.
For electrical installation, make sure to follow the enclosed wiring diagram.
Supply lines to microprocessor controller and actuator must meet the conductor cross-section as specified in the VDE regulations.
For low voltages (set point/actual value signalling cable) use
shielded
conductors of minimum cross-section
0.5 sq.mm. and maximum length of 1000 m.
Make sure to connect one end of the shielding to the housing mass (earthing terminal).
Never attempt to modify the internal wiring of the actuator.
Never attempt to modify the internal wiring of the actuator.
