Intermittent Mode / Rotation Direction; Beep; Error 5 - IKA C-MAG HS 7 control Betriebsanleitung

/// Intermittent mode / rotation direction

Intermittent mode
Intermittent mode consists of regular, cyclical interruption of the stirring
function. The run time (0 / 10 sec – 10 min, 10 sec steps) and pause time
(3 sec – 5 min, 1 sec steps) should both be set. When the intermittent mode is
activated, a decimal point in front of the first letter appears on the display (18).
Rotation direction
You can select the continuous rotation. Therefore the time has to be set to
00:00:00 by pushing the rotating knob. (D). Afterwards the rotation direction
(clockwise or counterclockwise) can be selected by turning the rotating knob
(D). Alternative to the continuous rotation, you can set the automatic reverse
rotation function. Then the rotation direction changes after each pause.
In this way the magnetic rod is captured and any liquid still rotating is gradually
slowed down. Then the drive accelerates to the target speed.

/// Beep

The menu item "Beep" allows the user to turn on / off the sound that occurs
when the timer reaches 00:00:00 or an error message appears.

/// Error 5

Providing safety protection, Error 5 is taken to recognize that the sensor
has not been placed in the medium when the heating is switched on.
Note! ( )
You can set a value from 1 to 30 min for this time limit depending on the
application. If time limit is set to 0 min, the Error 5 detection is disabled.
Caution! ( )
This function will only be active if:
› sensor temperature is < + 50 °C
› difference target temperature / sensor temperature > 5
/// Expiration of timer
You can specify the procedure of heating and stirring function if the timer
achieves 00:00:00. Next to the visually / audible information you can decide
independently if the heating and stirring should be stopped automatically if
the timer is expired or should continue.
Caution! ( )
If heating and stirring function is set to stop after timer is expired,
you have to ensure that there is no heat distortion for this application.
If heat distortion is not desirable, the stirring function should continue.
