PROGRAMMER PR 5-3T 
The microprocessor controlled ramp regulator offers a comprehensive time/temperature regulation for the high temp. hot plate. Pressing the START key activates a program of up to 5 ramps. Max. 5 ramps (consisting of ramp time, constant temp. and time of constant temp.) can be programmed. 3 program sets can be loaded into the non-volatile memory. A programmed lead time enables the activation of the start up to 99 hours in advance. 
Every temperature and time parameter can be selected with its awn key. Consequently the setting is easy and clear. It is possible to pass over single ramps by setting the according 
parameter to '0'. Every set value can be controlled during a program. 
Back-up by an EEProm. The device is equipped with a change-over switch to continuous control; buzzer signal at the program. 

Equipment of PR5-3T and TR 28-3T 
2-poled main switch; individual adjustment of proportional range, derivative/integrating factor and cycle time; control range limitation (to avoid the setting of values not useful or harmful to an application); contact maker input, actual value correction, junction bush for high temperature hot plate, wattage power control 1...100%, unmterrrupted switching. 
Both regulators show the actual value constantly. Furthermore the programmer shows the remaining time of a ramp. When the SET key is pressed, the display changes to show the setpoint. 
On request the devices are available with a temperature limiter to avoid superheating.
