The life of electronic equipment like Temperature Controllers is influenced not only by the life determined by the relay switching count but also by the life of internal electronic components. The service life of components is dependent on the ambient temperature: The higher the ambient temperature becomes, the shorter the service life becomes, and vice versa.

For a two-point shift, the shift amount for the lower limit and upper limit are set separately and both the measurement values and the slope are shifted.

    One-point Shift 1,2,3... 1. In the configuration shown in Figure 1, bring the SP to near the value at which the temperature of the control target is to be controlled. Let's as- sume that the control target temperature (C) and the control target temper- ature (B) are the same.
  • Page 58 1,2,3... 1. The Controller readout will be shifted at two points, near room temperature and near the value at which the temperature of the control target is to be controlled. For this reason, bring the control target temperature to near room temperature and to near the SP, and check the control target temper- ature (B) and Controller readout (A) at both points.
  • Page 59 We will assume that when the room temperature X1 is 25 ° C, the readout on the Controller Y1 is 40 ° C, and when the temperature near the SP X2 is 110 ° C, the readout on the Controller Y2 is 105 ° C.

    4-7-1 SP Ramp The SP ramp function controls the rate of change of the SP. If a change larger than the rate of change is specified when the SP ramp function has been enable, changes in the SP will be limited as shown below. Thus, when changes are made to the SP with the SP ramp function enabled, control is performed according to the rate of change rather than the target value.

If the refresh cycle for data from the external sensor is longer than the “re- mote PV communications wait time,” the E5ZN will determine that the ex- ternal sensor has been disconnected, and an input error will occur.
