During the controller insertion into the system housing, one must pay
attention that the controller plate edges were placed in the housing guides
and next, one must insert the controller into the housing so that it becomes
levelled with the other controllers, and screw it.
It is forbidden to push and pull BR11 controllers when the
main power switch in turned on!
Before connecting the supply voltage, one must strictly carry out checking of
the electrical connection conformity.
One must measure the resistance of all heating zones and the isolation
resistance both between individual circuits and the PE wire.
After confirming the correctness in installation connections on
the injection mould, one must connect connection cable plugs with appro-
priate sockets of multiple-contact connectors.
After turning the main supply on, successive heating zones are
turned on by push-buttons situated on the controller frontal plate.
After turning controllers on, one must set the required temperature value
in the way described in the user’s manual of BR11 controllers.
In order to pull out the BR11 controller from the system housing, one must
absolutely turn the main supply off, and next undo fixing nuts and take
the controller out, catching it by the holder.
1.3. Way of Serial Interface connection
To obtain the connection with the PC computer of IBM class an inter-
face card is indispensable, a RS-232/RS-485 converter (e.g. PD51)
or USB/RS-485 converter (e.g. PD10).
The RS-485 standard allows to the direct connection of 32 devices
(controllers) on a single serial link of 1200 m long. For the connec-
tion of a higher number of devices it is necessary to apply additional
intermediate-to separating systems. One must carry out connections by
shielded wires.
Each BR11 controller must have set the same transmission mode and
speed and different addresses.
