When connecting the relay wiring, do so with complete understanding of what the process requires of the instrument. The instrument has dual DPDT or single 4PDT relay output contacts dependent on the jumper configuration for each alarm switch point. For the relay logic, refer to Figure 2-5.
CHAPTER 3 - OPERATION FLUID COMPONENTS INTL 3. Operation Caution: The control circuit contains electrostatic discharge (ESD) sensitive devices. Use standard ESD precautions when handling the control circuit. See Chapter 2, Operation, for ESD details. Factory Default Jumper Configuration Unless a custom factory setup or calibration is specified, the instrument is delivered in a standard factory configuration. The standard default jumper configuration is shown in Table 3-1. Table 3-1.
FLUID COMPONENTS INTL CHAPTER 3 - OPERATION Figure 3-1. 5294 Control Circuit Jumper Locations The reason for operation in the above extreme conditions is that the input signal range is at the widest point making the alarm set point adjustment easier to perform. If the heater does cycle the operator may need to use the next lower wattage setting. In some applications it is desirable to set the heater wattage high, even though the sensing element goes into the heater cutoff mode.
