Additional heat generator demand
Function:
With the “enable signal” (floating contact), an on-site
peak load heat generator (oil or gas boiler) is activated
when the supply temperature falls below a certain value.
The temperature of start and stop points can be selected
freely on the controller. The controller and control unit
for the oil or gas burner is not included in the standard
delivery.
Standard delivery:
Floating contact for enabling an additional heat generator
Submenu on touchscreen
External drive switching without light barrier
Activation of an external conveyor drive or a rotary lock
valve without reversing. The motors are protected against
overload.
Standard delivery:
Motor overload relay/contactor combination for drive
motor fully integrated in control panel
Input in control panel for safety limit switch on
maintenance
cover
Output in control panel for external conveyor drive
Note:
The customer is responsible for delivery and installation
of the safety switches of the external conveyor drive.
Note:
Only with a defined limited material supply
(upstream screw conveyor).
The electrical output data of the existing conveyor
device (kW, amps, volts) must be stated.
External drive switching with light barrier
Activation of an external conveyor drive without reversing
The integral light barrier interrupts the upstream charging
when there is a risk of overfilling in the inlet. The motors
are protected against overload.
Standard delivery
Motor overload relay/contactor combination for drive
motor fully integrated in control panel
Input in control panel for safety limit switch on
maintenance
cover
Output in control panel for external conveyor drive
Infrared light barrier installed at the screw conveyor inlet
Note:
For the activation of a screw conveyor with external
motor downstream of the external discharge
Note:
The electrical output data of the existing conveyor
device (kW, amps, volts) must be stated.
