I-137 Temperature Controller Installation ■ Connection Diagrams • Voltage output (control output) is not electrically isolated from internal circuitry. Therefore, when using grounded thermocouples, do not ground control output terminals. (Doing so may result in temperature measurement errors due to unwanted current paths.) • There is basic insulation between the power supply inputs and outputs for this product. If reinforced insulation is required, connect the input and output terminals to equipment without any exposed charge-carrying parts, or to equipment with basic insulation sufficient for the maximum oper- ating voltage of the power supply and the inputs and outputs. Using with the E5ZN-SCT24S-500 Using with the E5ZN-SCT18S-500 E5ZN-SDL Note: Purchase either a P2CF-11 or a P3GA-11 Socket separately.

■ Examples of Functions Using as a Temperature Input Signal Converter Transfer Output Types • The ten types of data shown below can be allocated for transfer output using the control output 1 allocation, control output 2 alloca- tion, auxiliary output 3 allocation, and auxiliary output 4 allocation (initial setting level). • Transfer output is supported by analog output models only. Note: Control outputs 1 and 2 use current output and auxiliary out- puts 3 and 4 use linear voltage output. Transfer Output Scaling • The range set by the transfer output upper limit and transfer output lower limit (initial setting level) can be scaled to the output range for the transfer output (4 to 20 mA DC or 0 to 20 mA DC for control out- puts 1 and 2, and to 1 to 5 VDC or 0 to 5 VDC for auxiliary outputs 3 and 4). • The scale can be expanded by setting a small range between the transfer output upper and lower limits. Reverse scaling can be per- formed by setting the transfer output upper limit to a value smaller than the transfer output lower limit. The following figure shows a scaling example where the heating control MV transfer output is scaled to 1 to 5 VDC. Example: Scaling to 1 to 5 VDC Reading Temperatures for Multiple E5ZN Units With conventional models, if the present temperature is read from multiple Temperature Controllers using host communications, there are time differences in the process temperatures read from each Temperature Controller, making it difficult to obtain concurrent data. With the E5ZN, the PV hold function can be used to ensure that the data is concurrent to within 500 ms. PV Hold The PV hold function temporarily stores the present temperature for that moment as the PV hold value, when the "PV hold" operation command sent by host communications is received. (See fig. 1.) Fig. 1 Note: 1. PV hold values are overwritten every time the "PV hold" op- eration command is executed. Once the PV hold values have been read for channels that require simultaneous reading of present temperatures, execute the next "PV hold" operation command. 2. The "PV hold" operation command cannot be executed and the "PV hold value" cannot be read from the E5ZN-SDL Set- ting Display Unit. 3. When the power is turned OFF, the PV hold values change to 0. ch1 ch2 Transfer output for ch1 set point Transfer output for ch2 set point Transfer output for ch1 ramp set point Transfer output for ch2 ramp set point Transfer output for ch1 process value Transfer output for ch2 process value Transfer output for ch1 heating control MV Transfer output for ch2 heating control MV Transfer output for ch1 cooling control MV Transfer output for ch2 cooling control MV 0 5 1 80 100 10 Transfer output (V) Transfer output lower limit Transfer output upper limit Heating control MV (%) Example 2: Displaying the ch2 Process Values on an External Meter Using Transfer Output Temperature Controller: E5ZN-2C@F03P-FLK (current output, platinum resistance thermometer input) Meter: K3MA-J 24 VAC/VDC (Process Meter) Temperature Controller Settings: Sensor input type (initial setting level): 2 (platinum resistance ther- mometer, 0.0°C to 100.0°C) Control output allocation 2 (initial setting level): 17 (process value transfer output for ch2) OUT2 transfer output upper limit (initial setting level): 100.0 (°C) OUT2 transfer output lower limit (initial setting level): 0 (°C) Current output type (initial setting level): 0 (4 to 20 mA DC) Meter Setting Example: Inputs for 4 to 20 mA DC are scaled to 0.0 to 100.0°C.

If the product is installed inside a control panel, the temperature around the product (and not the temperature around the control panel) must be kept below 55×C. With electronic devices like the E5ZN, the service life will depend not only on the number of switching operations performed by the relay but also on the service life of the internal electronic components. The service life of these components depends on the ambient tempera- ture; it will be shorter if the ambient temperature is high, and longer if the ambient temperature is low. For this reason, the service life of the product can be lengthened by keeping the inside of the E5ZN at a low temperature. If several Units are mounted side-by-side or are arranged vertically, the heat generated may cause the internal temperature of the Units to rise, reducing service life. To prevent this, take steps to ensure that the Units are cooled, such as installing fans. Ensure, however, that the terminals are not also cooled, otherwise correct temperature measurement will not be possible. Measurement Accuracy When extending the lead wires for thermocouples, use a compensat- ing conductor appropriate for the type of thermocouple used. When extending the lead wires for platinum resistance thermome- ters, use lead wires with a low resistance, and make the resistance in the 3 lead wires equal. Mount the E5ZN horizontally. If significant errors occur, check that input compensation has been set correctly. Waterproofing The enclosure ratings are given below. Parts for which the enclosure rating is not clearly indicated, and parts with IP@0 ratings (where @ is not 0) do not have waterproof specifications. • Temperature Controller: IP00 • Terminal Unit: IP00 Mounting and Dismounting • To mount using a mounting track, first hook part A (see below) onto the track and then push down on part B. • To dismount, insert a flat-bladed screwdriver into part C, pull the hook down, and then lift the bottom part of the E5ZN upwards. • Mount the E5ZN at least 30 mm away from other devices to ensure easy mounting and dismounting. Note: Refer to the following manual for precautionary information and other information necessary to use the E5ZN: E5ZN Temperature Controller Operation Manual (Cat. No. H113). Stopper 30 mm min.
