ELECTRICAL CONNECTION
4.6.1.
4.6.1 Mains voltage
The
C-TOP
control head has been designed to be connected to different voltages:
DC or direct current: 24V
AC or alternating current: 24/48/110/220V
The head is supplied from the factory for a predetermined voltage. If the mains voltage proves to be
different, the electrical components must be changed (solenoid valves, proximity detectors and
electric plate).
4.6.2 Electrical components
All the electrical components used in the
C-TOP
head have a built-in pluggable connector which avoids having to carry out any
further interventions or wiring. The printed wiring board has, as a standard feature, the capacity to plug in up to 3 solenoid
valves (V1, V2, V3) and 3 proximity detectors or microswitches (S1, S2, S3).
The default assembly is as follows:
Output:
24V
– general output (+ pole for DC)
GND
– normal or mass for DC.
24/48/110/220 V (2 wires) for alternating current, either of the
wires can be connected.
Solenoid valves:
signal inputs, to the control panel or PLC
V1
– first solenoid valve (Simple Effect drive)
V2
– second solenoid valve (Double Effect drives)
V3
– third solenoid valve (MixProof drives)
Detectors:
signal outputs, to the control panel or PLC
S1
– Open valve detector position (Green LED)
S2
– Closed valve detector position (Red LED)
S3
– MixProof valve detector position (Yellow LED)

AS-INTERFACE ELECTRIC CONNECTION
AS-i interface is a fieldbus system that allows to interconnect a net of actuators and binary sensors (slaves) with a control
device of a higher level (Master). The interconnection is carried out by means of a preformed cable. The preformed cables serve
for information transmission as well as for power supply of the solenoid valves and sensors. The AS-i version C-TOP unit must
always be installed with inductive switches and direct current of 24V.
The C-TOP AS-i unit is supplied with the totally prepared cabling to avoid any intervention.
The standard option of the connection to bus is by means of a insulation displacement connector with a 2m cable.
The AS-i cards with printed circuit are prepared for up to 4 solenoid valves and 4 proximity switches.
