Setting The Safety Temperature Limit - IKA C-MAG HS 7 control Betriebsanleitung

// Setting the safety temperature limit

The maximum achievable heating plate temperature is restricted by an
adjustable safety temperature limit. Once this limit has been reached,
the device stops heating.
Caution! ( )
The denominated temperatures should always refer to
the center of the hotplate.
Warning! ( )
The safe temperature limit must always be set at least + 25 °C
lower than the fire point of the media to be processed!
The adjustable maximum heating plate temperature must always
be set at least + 15 °C under the set safety temperature limit.
Setting range: [+ 100 °C] to [max. SET temperature + 650 °C]
Factory setting: [max. SET temperature + 650 °C]
