Page 13: Examples Of Application
POWER TERMINAL BLOCK CONTROL TERMINAL BLOCK In this application the CODE 310S operates at current CLOSED-LOOP control through TA. The controlled current, and therefore the torque, is that of the Rowan motor that must wind and unwind material, maintaining a constant pull as coil diameter varies. -

(terminals 6-9) 0VDC at 0°C and +10VDC at 40°C. At the CODE 310S control terminal block it is moreover possible to connect a minimum ventilation potentiometer with which you can set fixed minimum ventilation and fixed maximum ventilation to limit maximum cooling - this is done independently of automatic temperature control. - Page 15 CODE 251/92 acts as a transducer for the NI100 probe and supplies at output (terminals 6-9) 0VDC at 0°C and +10VDC at 40°C. At the CODE 310S control terminal block it is moreover possible to connect a minimum ventilation potentiometer with which you can set fixed minimum ventilation and fixed maximum ventilation to limit maximum cooling - this is done independently of automatic temperature control.
