Operating and installation instructions
Thrust actuator ARI-PREMIO
5.5.12 Phase control relay
The phase control relay monitors phases L1, L2 and L3 in the mains input supply. The
reversing contactor is only activated by the phase control relay providing phases L1, L2 and
L3 are connected correctly. This protects the thrust actuator.
5.5.12.1 Installing the phase control relay
The phase control relay is installed in the ARI-PREMIO next to the reversing contactor. It is
only possible to use the phase control relay in conjunction with the reversing contactor. It
cannot be combined with the dTRON 316 temperature controller in the actuator.
Proceed as follows to install the phase control relay:
Switch-off the mains voltage and take measures to prevent it being switched back on
inadvertently.
The electrical connection procedure as described in „5.4.3 Connection“ and „5.5.11
Integrated reversing contactor“ is supplemented by the following steps:
- Attach the phase control relay next to the reversing contactor (Fig. 20).
- Connect the three-phase connection L1, L2, L3 and the 3-step input signal as shown in
Fig. 10.
