Page 2: Heating Control
Inputs and Outputs : The 1TT device has an input to show the temperature (PV) and two digital outputs (OUT and ALARM). Timer relay contact The small clamps are used as in the following table: 1t regulation channel (SP) Probe input TC 1 (3 - 4+) Output SP (19 - 20) Alarm AL (17 - 18) Timer relay contact Relè (15 - 16) Heating control: If the adjustment channel has been set to heat mode, the temperature control is obtained by the complete PID algorithm or the ON-OFF algorithm with hysteresis. The Act parameter must be set to Hot in order to select the heating action: the activation of the control output causes an increase in temperature because it is connected to a heating element . The selection is made by setting the proportional band ( PB ) : • Setting value 0 ( zero) will enable the ON – OFF adjustment • Setting any value other than 0 will enable the PID adjustment The aforementioned settings are summarized in the table below: Simbolo ON-OFF PID Proportional Band If is set to 0 it will enable ON-OFF PB > 0 – proportional band PID Integral Time Integral Time PID Derivative Time Derivative Time PID (Td=-1 automatic Td= Ti/4) Positive Hysteresis HSO > 0.1°C Negative Hysteresis HSU < 0.1°C... - Page 3 Manual modes (pulse generator) The instrument has two manual modes that exclude the control algorithms and run the control elements at constant power: • Manual mode always on (also with temperature probe); • Manual mode only when there is an error with the temperature probe. Select manual mode (always on) by selecting the parameter MAN = 1 (the MPE parameter is ignored). To select manual mode only when there is an error with the temperature probe by selecting the parameter MAN = 0 and MPE = 1. In both cases the percentage of activation control output is set via the OUT parameter (percentage of the cycle time normally used).
