• Fan motor 1: max. 5A 220 ÷ 240V AC ±10% 50-60Hz.
• Fan motor 2: max. 5A 220 ÷ 240V AC ±10% 50-60Hz.
Characteristics
• Self-extinguishing NORYL container.
• Front panel protection grade in polycarbonate: IP65 (IP66 on request).
• Protection level of rear panel on terminal block side: IP20.
• Display with light segments.
• Measurement and control of current absorbed by fan motors on two
independent lines.
• Auto-calibration of rated current absorbed by each ventilation line.
• Generation of warning signals in case of greater or lower current
consumption than the nominal current measured upon auto-calibration,
overtemperature of at least one fan motor.
• Operating mode: automatic (via remote control of ventilation system),
manual, channel scan.
• Maximum management flexibility and simplicity of programming.
• Permanent storage of the programmed values and the data reached by each
channel (historical thresholds and maximums).
• Control unit working temperature from -20°C to 60°C.
• Maximum permissible ambient humidity 90% non-condensing.
• Electrical connections on polarized removable terminal blocks.
• Technical manual in two languages (other languages on request).
• Construction in conformity with regulations .
• Input filter against regulation disturbances .
• Tropicalization (optional).
Do not carry out dielectric strength or partial discharge tests on electrical
machines with the control unit inserted, if possible avoid directly connecting the
control unit to the secondary of the transformer to be protected, it may happen
that, without protection, when the circuit-breaker closes downstream of the
transformer, overvoltage occurs which may damage the equipment. This is
more evident if the power supply voltage of the control unit is 230 V AC and if
there are power factor correction capacitors.
