3. Introduction Heater Jacket Control Unit
Heater Jacket Control Unit (HJCU) is designed for use together with one Heater Jacket (HJ).
HJCU monitors and controls the Heater Jacket temperature. The temperature on HJ1can easily
be altered. HJCU has two alarm outputs, upper limit and lower limit.
HJCU-COM communicates with RS-485.
4. Installing Heater Jacket Control Unit
Check the main fuse, make sure it’s of the correct value in relation to the mains voltage and conforms to
specifications for the HJ. See “Technical specification”.
Mount the HJCU on a vertical wall with screws intended for the supporting surface. Use the screw holes
under the cover screws.
Mount the HJCU so that the mains switch and regulator are not blocked.
Connect the HJ to the HJCU using “Extension cable kit”.
If used, connect the alarm cable to the HJCU. See “Alarm description” & “Technical specification”.
Fit the HJ as described in the manual “Heater Jacket HJSA & HJSB”
Connect Mains to the HJCU using the correct supply cable to an earthed electrical outlet socket.
Requisite knowledge is required.
Press the power switch. The equipment is now operational.
The default factory setting of SV2is 80ºC. SV can be changed within the range 30ºC to 140ºC
Should an error message be displayed on the regulator see the manual Omron E5CN Temperature controller.
In the event of a fault see “Fault tracing”

Alarm description
Alarm outputs may be connected to external devices. Use the supplied connector for connection of alarms.
Use approved cables with an outside diameter of Ø6–8 mm, max wire area 1.5 mm2(see “Material selection”)
We can supply you with an Alarm cable (HJAC, se Accessories / Spare parts) with following connections:
Black to pin 1, Brown to pin 2 and Blue to pin 3.
Connection terminals for alarms connectors see the section “Connections”
For more information read the instructions in the manual for Omron E5CN Temperature controller.
Replacing the supply cable
Read the text in the section “Warning” before replacing the supply cable!
Also, remember that the earth wire should be the longest so that it releases last.
Replacing the supply cable: With 230 VAC connect: Black to L, Blue to N and Yellow/Green to .(Earth)
With 115 VAC connect: Black to L, White to N and Yellow/Green to .(Earth)

Regulator Communication
The communication connector on HJCU-COM can be connected to a PC (Personal Computer)
via a PC-Transformer5. TCViews is a logging program that gives the user a possibility to view 32 HJCU-COM
at the same time on a PC screen. TCViews provides you with a possibility to operate, monitor and change
temperature controller parameters. With TCViews you create projects, add users with different access rights,
change operating parameters, log and view data (temperature graphs according to time scale are available).
More information can be found in TCViews manual.
For further information about the regulator see the manual for Omron E5CN Temperature Controller.
