ZED24 Control unit
The electronic control unit ZED24 can be used to control 1 or 2 motors with a power not exceeding 120W+120W.
The following types of installation are possible:
A) 1 Motor ZED24 with built-in control unit: In fig.1, with reference to the “A” general scheme, connect the accessories as
indicated in the “C” diagram.
B) 1 Motor ZED24 with built-in control unit and one motor ZED24 without control unit: In fig. 1, taking as a reference the “A”
and “B” general diagrams, connect the accessories as per “C” diagram and connect the two motors as indicated in the “D”
diagram shown in Fig. 2.
C) 1 Control unit ZED24 fitted to wall and two motors ZED24 without control unit: In fig. 1, taking as a reference the “A” and
“B” general diagrams, connect the accessories as per “C” diagram and connect the two motors as indicated in the “E” diagram
shown in Fig. 2.
IMPORTANT: Should two motors be used, connect the limit switches of one single motor to the control unit.
GENERAL WARNINGS
a) The wire connections and the operating logic should be in compliance with regulations in force.
b) The cables featuring different voltage should be detached, or adequately insulated by an additional insulation of at least 1 mm.
c) The cables should be further fastened in proximity to the terminals.
d) Check all connections before powering the unit.
e) Check that setting of the Dip-Switches are the required ones.
f) Normally Closed inputs which are not in use should be short-circuited 230VAC – keep to phase/neutral).
