Switching "On" and "Off"
The main Power Switch is a rotary Switch at the back of the
cabinet. This Switch is sufficiently rated to disconnect the total
load current during switch “On” and switch “Off”. You can use a
suitably- sized padlock, or similar device, to lock the switch in the
“Off” position to prevent operation during maintenance.
Although the main switch has the capacity to switch the whole
system “Off”, we recommend that you only do this in an
emergency situation. A sequenced method for switching “On” and
“Off” protects the controller and keeps the switched load to a
minimum to extend the life of the main Isolator.
Switching On
Once the controller card is on, it gets into “Run” mode
automatically to start heating the tool.
Switching Off (or Shutting Down)
We recommend that you use the controller to shut down the
heating load, and only use the main isolator to switch off the whole
system once it is idle.
1. Shut down the heating
Use I/O switch to turn off each controller card.
2. Shut down the Controller
Now use the Main Rotary Switch on the cabinet to isolate all the
power from the whole system.
