• When the adjusted control parameters Xp, Tn and Tv are too high,
this requirement may not be given with respect to on how much the
setpoint temperature has to change. In this case, prior to carrying out
an identification in the „OFF“ state, set the control parameters to
lower values.
Recommended setting for internal control:
Xp = 1.0 °C
Tn = 80 s
Tv = 8 s
Setp.: 50.00°C

Setpoint
The programmable controller provides three possibilities for the setpoint
selection. The selected mode is indicated on the DIALOG-DISPLAY
(LCD).
Possible parameters:
keyb- via keypad (working temperature T) or via the integrated
programmer.
eprog - via the analog interface REG+E-PROG (31) through an external
programmer.
RS232 - via the serial RS232/RS485 interface (30) through a PC or
superordinated data system.
Autostart
Note:
The M1control electronic has been configured and supplied by JULABO
according to N.A.M.U.R. recommendations. This means for the start
mode, that the unit must enter a safe operating state after a power
failure (non-automatic start mode). This safe operating state is indicated
by „OFF“ or „rOFF“, resp. on the MULTI-DISPLAY (LED). A complete
shutdown of the main functional elements such as heater and circulation
pump is effected simultaneously.
Should such a safety standard not be required, the AUTOSTART
function (automatic start mode) may be activated, thus allowing the start
of the programmable controller directly by pressing the mains power
switch or using a timer.
Possible parameters:
on - AUTOSTART on
off - AUTOSTART off
