The control electronics offer two ways of adjusting a setpoint.
1. Adjustment of setpoint using the keypad
or the integrated programmer.
2. Adjustment of setpoint via the serial interface RS232 using a PC or a
superordinated process control system.
The topline of the VFD-DISPLAY shows a bright „
remote control discontinued.
IMPORTANT: additional measures for remote control
Connect the circulator to the PC using an interface cable.
Check the interface parameters of both interfaces (Thermostat and PC) and
make sure they match.
(refer to Setupfor remote control page 93)
Notice:
The circulator has been configured and delivered by JULABO in accordance
with the NAMUR recommendations. This means for the start mode that the
unit must enter a safe operating status after a power failure. This safe
operating status is indicated by the message „OFF" or „R OFF" on the VFD
COMFORT-DISPLAY.
A complete, all-pole shutdown of the main functional elements such as heater
and pump motor is effected.
The values set on the circulator remain saved and the unit is restarted by
pressing the start/stop key in manual control.
In remote control mode the values need to be resent by the PC via the
interface.
If such a safety standard is not required, the NAMUR recommendations can
be bypassed with the AUTOSTART function thus allowing a direct start of the
circulator by pressing the mains switch or using a timer.
