Function description 5 Function description The PMD s10 monitors the set upper and lower true power limit on a single or three phase supply or on the DC supply. The unit operates in accordance with the principle of Aron cir cuit. } Relay outputs (K1 and K2): K1 and K2 operate in normally energised mode. In their default state, auxiliary contacts 1114 and 2124 are closed and auxiliary contacts 1112 and 2122 are open. Normally energised mode is the default setting.

Current transformer CT 100 : 1 and no voltage transformer VT 1 : 1 Pmax = (1.0 W … 11.
Installation 6 Installation } The unit should be installed in a control cabinet with a protection type of at least IP54. } Use the notch on the rear of the unit to attach it to a mounting rail. } In environments exposed to heavy vibration or when installing on a vertical mounting rail (35 mm), the unit should be secured using a fixing element (e.g. retaining bracket or end angle). } Push the unit upwards or downwards before lifting it from the mounting rail.
Commissioning 7 Commissioning 7.1 Wiring Please note: } Only wire the unit when the supply voltage is switched off! } Use copper wiring. } To prevent contact welding, a fuse should be connected before the output contacts (see Technical details [ 31]). } Ensure that the cables are laid carefully, because an open circuit in the measuring cir cuit will cause the unit to malfunction. } Information given in the Technical details [ 31] must be followed.
Commissioning With continuous currents of > 12 A the measuri8ng current has to be measured via an ex ternal current transformer. With voltage > 500 V the voltage has to be measured via an ex ternal voltage transformer. 7.3.

If you change the parameters, the Insert SIM Card message will reappear. When the chip card is inside the unit, 7.5.3.1 } the chip card is checked to verify the device identifier and ensure that the data is identical. } Unit parameters are automatically saved to the chip card during operation.
