Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collecti on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.
Purpose
The CZF-334 phase loss microprocessor sensor without neutral
wire is designed to protect electric motor powered from the
3-phase network in following cases:
» voltage loss in at least one phase;
» voltage drop in at least one phase below 320 V;
» voltage increase in at least one phase above 480 V;
» voltage unbalance between phases above a preset vlalue.
The sensor correctly measures the true rms value of the
voltage (TrueRMS), even when the power supply voltage
is (disturbed) distorted.

    Functioning A correct supply voltage is signalled by the lighting of the green LED. A voltage drop below 320 V, or a rise above 480 V on at least one, any phase, or a voltage asymmetry above the set value is signalled by the green LED not being lit.
  • Page 3 Signalling Signalling Description Correct network parameters, the relay is on. Countdown to switching on or deactivation of the relay (depending on the current state of the output). Asymmetry or voltage threshold exceeded. Relay switched off (voltage value of either phase below 320 V or above 480 V or asymmetry above the set value).

  • Page 5 If a voltage drop below 320 V or a rise above 480 V is detec- ted, the relay will be switched off with a delay of 1 s. The diode corresponding to the phase that exceeded the voltage threshold will be extinguished. If the phase voltages return to the correct values, the relay will be switched on after time T2.
