A. Serial Network Connection
(previously Master/Slave Connection)
NOTE: ONLY AIR CURTAINS FROM THE SAME SERIES CAN BE
NETWORKED TOGETHER. IF UNITS FROM DIFFERENT SERIES
ARE NETWORKED OR ARE INCOMPATIBLE, AN ER61 WILL
DISPLAY EVERY TIME A COMMAND IS ENTERED.
Serial Network Connection Operation
For Serial Network Connection a serial cable connection must
be made between all Intelliswitch™ controls of each air curtain
to be linked. Once air curtains are linked all Menu settings
made through any air curtain display or remote control will
transfer to all other linked air curtain. Parameter changes made
on any linked air curtain will update all other boards “live” upon
menu selections.
1.
All air curtains equipped with an Intelliswitch and
the Serial Communication Option have two RJ11
connectors (telephone plug) located in the wiring
compartment. Serial cable(s) with the corresponding
RJ11 socket (telephone jack) on each end are shipped
separately.
2.
Once the air curtains are installed, connect all units
that are to be networked together using the serial
cable(s) and either of the two RJ11 connectors in
each wiring compartment. For example, two units
networked together require one cable and leaves
an unused connector in each wiring compartment.
Three units networked together requires two serial
cables, leaves two units with one connector unused
in each wiring compartment and one unit with both
connectors used.
3.
A wiring diagram is included in the wiring
compartment of each air curtain and illustrates the
provision where the serial cable is connected to
network additional air curtains.
4.
Once all serial cables are connected and all air curtains
have power the units can be programmed from any
handheld remote or air curtain display on the network.
All program settings are included in the installation
instructions shipped with the air curtain.
5.
If the air curtains were purchased with the WiFi option,
when connected to the local WiFi network they can
be programmed from a smart phone using the Berner
app.
Serial Network Connection - Settings
When units with the Intelliswitch™ are operated in a network
there are three options available under the Programming Menu
that manage how they interact with each other.
•
Door Switch (door)
•
Thermostat (temp)
•
Stand By (Stby)
Each option can be set to “ind” or “ALL”.
“ind” = the option only is activated on this unit or independent
of the other units
“ALL” = the option activates ALL of the units connected on the
network
1. To access the Serial Network Connection hold the left
arrow for 5 seconds and “Pro” will display
2. Use the left/right arrows to locate the desired option
(door/temp/Stby)
3. When located, use the down arrow to enter into that
setting.
4. Use the left/right arrow to change the setting between
“ind” and “ALL”
EXAMPLE: Stand By function
If set to independent, when STOP is pressed only the unit
where STOP is pressed will stop. If set to ALL, all of the
connected units set to ALL will stop.
EXAMPLE: Door Switch function
If set to independent, the door switch connected to a unit will
only activate that unit. If set to ALL, all of the connected units
set to ALL will activate.
B. Remote Mounted Display Faceplate
-
for operation of the Intelliswitch™ through a remote mounted
display faceplate.
NOTE: Maximum mounting distance between the Display
Faceplate and the unit is 20’.
The unit MUST be factory
ordered with the remote mounted faceplate option.
When the remote faceplate option is ordered from the
factory the air curtain comes equipped with the
blank faceplate and 20’ ribbon attached. The Display
Faceplate is shipped loose ready for field installation.
1.
Locate the male end of the 14-conductor ribbon
cable in the wiring tray and run to the remote display
location. The cable is minimum CL2 rated and should
not need to be in conduit.
2.
Connect the ribbon cable to the 14-pin socket with red
stripe positioned on the top left when facing the front
of the display board.
3.
Mount remote faceplate to the wall.
4.
Reinstall the wiring tray cover.
C. Infra-red Remote Control
The handheld infra-red remote control buttons, layout and
operation are the same as that on the Intelliswitch™ air curtain
display (including multiple button presses) with one exception,
the Lock Button.
There is no need for multi-button press and hold for lock/un-
lock activation. The Lock Button will lock/unlock display in one
press.
The Infra-red Remote Control has a range of 15 feet.
