Page 7: Introduction
INTRODUCTION The compact microprocessor-controlled temperature controller type 70304G is mainly used for M&C components that have no temperature controller in their standard specification. If the temperature con- troller is ordered together with an M&C component, he already is parameterized and pre-programmed. -

Page 16: Self-Optimizing (Pid Action) Of Control Circuit
15.2 SELF-OPTIMIZING (PID ACTION) OF CONTROL CIRCUIT The controller type 70304G includes the option of self-optimizing. For the initial operation of all M&C components, this is necessary. For self-optimizing of the control circuit, the heating of the respec- tive M&C component must be reconnected to the appropriate con- troller terminals (see Figure 3). -
Page 17: Commissioning With Heated Foreign Components
After entering the parameters, a self-optimization, described in chapter 15.2, has to be operated. LOW TEMPERATURE ALARM AND EXCESS TEMPERATURE LIMITATION The controller type 70304G is adjusted and wired so that it uses relay 2 as a low temperature alarm output and relay 1 as an excess temperature limitation with permanent deactivation. -
