The maximum achievable heating plate temperature is restricted
by an adjustable safety temperature limit. Once this limit has been
reached, the device stops heating.
The safe temperature limit must always be set at least 25
°C lower than the fire point of the media to be processed!
(acc. to EN 61010-2-010)
The adjustable maximum heating plate temperature is at least 10
°C under the set safety temperature limit.
Setting range: [50 °C] to [max. SET temperature + 50 °C]
Factory setting: [max. SET temperature + 50 °C]

Setting the safety temperature limit
After switching on the device, the safety temperature limit can be
adjusted using a screwdriver.
Do not turn the setting screw beyond the clockwise or anticlo-
ckwise stop. This will cause irreparable damage to the potentio-
meter.
• Set the main switch to the ON position.
• Using the screwdriver supplied, turn the "Safe Temp" setting
screw to the clockwise stop.
• Use the temperature rotating / pressing knob to set the target
temperature to the desired "Safe Temperature" and wait until
the temperature is achieved.
• Turn the "Safe Temperature" setting screw slowly anticlockwise
until the heating function switches off and the display shows
Er25 .
• The "Safe Temp" value is displayed on the screen.
Setting the safety temperature limit has to be done as described.
The value "Safe Temperature" shown on the display only serves
for visualization.
