Remote rack actuator
This mode allows you to control the solenoid valves of the rack in the
area associated with the pumping station via one or two "remote area"
cabinets controlled in serial sequence via the J23 port of pCO5+.
This configuration is particularly useful if the rack is located away from
the pumping station, since it allows to bring the control signal via the
only serial cable in the rack area, reducing the number and length of
the cables of the solenoid valves between the rack and the device that
physically controls it (the remote area cabinet).
To enable the function, proceed as follows:
Electrical connections:
•
Connect the expansion (or two expansions) serially in port J23 of the
pCO5+ as follows:
pCOe
FBJ/J23
•
Connect the control signals used for the cabinet configured as "Remote
expansion/Actuator 1"
•
Connect the solenoid valves to the remote area cabinet that controls
them. If two cabinets are used, distribute them evenly. For example,
in the case of the first step with 6 collectors, connect three solenoid
valves to the first expansion cabinet and three solenoid valves to the
second cabinet.
Software configuration:
•
On the pumping station, enable the use of the remote actuator on
the Bbc09 screen: the software automatically establishes the number
of required actuators (1 and 2) based on the number of collectors
present, and alerts the user via a dedicated pop-up window
Configure the first slave as "Expansion/Remote actuator 1" and the second
one (only at request) as "Expansion/Remote actuator 2"
Note: if you are using this mode, the probe readings of the main
control (U1), limit (U2), auxiliary (U3), heat recovery signal (U5), rack
temperature (U8) and the ventilation solenoid valve are transferred to the
remote area cabinet configured as "Expansion/Remote actuator 1".
Remote area expansion
The software installed on the remote area cabinet, based on the number
of set collectors, automatically determines whether it is necessary to add
a second cabinet, used as an expansion for the proper management of
the solenoid valves. The system is pre-configured based on the number
of set collectors. The following are necessary to enable the feature:
Electrical connections:
•
Connect the J23 port of the remote area cabinet that requires
expansion to the BMS2 port of the cabinet configured as expansion,
as follows:
•
Connect the adjustment probes and the ventilation valve (if present)
to the remote area cabinet and distribute the solenoid valves between
the two cabinets. For example, in case of a step with 6 solenoid valves,
connect three to the first cabinet and three to the second cabinet.
Software configuration:
•
The remote area cabinet, based on the number of set collectors,
establishes if it is required to expand and alerts the user via a dedicated
pop-up window
•
Configure the slave used for the expansion as "Expansion/Remote
actuator 1"
