7-8. Heating Parameters
Figure 7-15. Heating Parameters Screen
Heating Parameters Screen:
Heating Parameters screen is a read-only screen that shows limits applied to various electrical parameters. You may set some limits on the
Adjustment Limits screen in the System Menu. The Heating Parameters screen also shows limits associated with any attached tool and the
heater itself.
The top of the screen shows the TC readings. If a control TC is not sending a reading, its background turns red. At top right, a recording indicator
flashes while data is being recorded.
Actual Parameters
This column shows actual parameters while heating. Actual parameters will often be less than heater limit due to coil configuration or the part
reaching temperature and requiring less heat. When one of the actual parameters reaches the heater limit value, output is limited and the rest of
the Actual parameters will be below the Heater Limit value.
System Limit
In some situations, users may have adjusted the system limits for a specific application to limit one or more of the parameters. The adjusted limits
are in the second column.
Tool Limit
ArcReach heating tools communicate their identity and power limits to the TC extension cable. The amperage limits for the tool are displayed in
the tool limit column. For example, the air
−
cooled heating cable displays 250/200 which means it can run at 250A for 15 minutes, then is restricted
to 200A continuous.
Heater Limit
The maximum parameters for the heating power source are displayed in this column. Depending on heating tool and part configuration, the actual
parameters may be less than the maximum. Output power will be limited when any of the amperage, voltage, frequency or temperature limits are
reached.
