The Soft Start Function
The Soft Start function is located within the Control
Menu page. The Soft Start function will operate inde-
pendently on each circuit.
To limit inrush current on the overall system, an inher-
ent characteristic of self-regulating/limiting heating ca-
ble, a proprietary Soft Start algorithm is applied during
system start-up. This will ONLY occur while the mode
of operation is set to AUTO and Soft Start feature is
turned ON. The Soft Start program will increment out-
put by 1% every 1 second until the desired tempera-
ture is reached or the output % achieves 100%.
After the Soft Start program completes its cycle, the
Automatic Control Mode of the system will return to
either PID or ON/OFF control, depending on what was
selected by the user. The Soft Start Program will not
function if the control mode is set to Manual.
The Comms Menu (Communications)
Security Level 3
The Comms Menu provides access to the settings for
Serial Communications, Modbus RTU/RS-485 or the
optional TCP/Ethernet Communications. These com-
munications settings include: Baud Rate, Parity, Mod-
bus ID, IP Address and DHCP.
Modbus RTU requires that you know or define baud
rate, character format (Parity), and slave ID (aka slave
address, unit number, unit ID). A mismatch in any of
these will result in no communication. Likewise, an in-
correct IP address will result in no communication on
an IP Network.
Note: See Modbus Communications Addendum for
detailed register addresses and other Modbus settings.
