CITIZEN 6 - 9/MC, CITIZEN 6+6 - 9+9/MC ELECTROMECHANICAL VERSION
8.3 Electrical diagram
Pictures 10-1, 10-2, 10-3, 10-4, 10-5, 10-6, 10-7 show the wiring diagrams of
the ovens Citizen 6/MC, 6+6/MC and Citizen 9/MC, 9+9/MC in the versions at
400Vac 3-N, 230Vac 3 and 230Vac 1-N.
N.B. For double chamber ovens Citizen 6+6/MC and 9+9/MC, version
230Vac 1-N, due to the high total electrical absorption, you have to handle
each single chamber as one-chamber ovens, each with separate electrical
supply. See wiring diagrams Pict.10-1, 10-4.
8.4 Adjustment for different feed voltages
Warning!
To adapt the equipment to work at different feed voltages
from that indicated on the initial set up label, three alterations have to be
made:
1) to the cabling for the resistor wires.
2) to the cabling for the feed to the control panel.
3) to the application of a new label.
Carry out three alterations with care as otherwise the equipment
may be unsafe.
1) Wiring of heating elements wires
Pull the plug out of the electric supply board. Remove the fixed guard from
the electric board. Disconnect all heating elements wires from the impulse
relays and reconnect them according to the wiring diagram identified for the
new electric supply; see Pict. 10-1, 10-2, 10-3, 10-4, 10-5, 10-6 and
Pict.10-7.
2) The cabling for the feed to the control panel
Detach the BLUE wire from the lower remote-control switch and reconnect it
as shown in Figure 10-1, 10-2, 10-3, 10-4, 10-5, 10-6 and Fig.10-7
depending on the voltage.
3) Application of the new plate
Apply an indelible plate carrying the specifications of the new electric supply
under the data plate (see Pict.4.3).
