IKA EH 4 basic - Manual (Page 11)

The desired safety temperature can be adjusted with the „safe
temp“ set screw. As soon as the desired safety temperature
is exceeded by a higher target temperature that has been set,
or if an error is encountered in the temperature controller, the
red pilot light (E) „Alarm“ lights up. The heater turns off per-
manently in this state, and the pump continues to run.
The unit can only be placed in operation again by switching off
and then back on again wizh the rocker switch (A).
After the target temperature has been reached, the safety
temperature is determined as follows:
• Using an appropriate tool, turn the „safe Temp“ set screw
(D) of the safety temperature controller until the switch-off
point to the left. The red pilot light (E) „Alarm“ lights up.
• Then turn the „safe Temp“ set screw (D) of the safety tem-
perature controller just slightly to the right.
• After you have turned the unit off and back on ag ain with
with the rocker switch , it is ready for operation.
