Installation Area As surrounding conditions affect the reliability and service life of the instrument, a favorable environment should be chosen. The following conditions are required. 1) Indoors 2) Altitude: 2,000 m or below 3) Temperature range: -10 to 50°C (Refer also to 10-6. -
Page 9: Wiring And Terminal Sizes
CAUTION If the instrument has the communication function, and data is written from the master equipment, trimmer adjusters and control input terminals may be disabled, making output adjustment impossible. For details, refer to the PAC46 SERIES COMMUNICATION INTERFACE INSTRUCTION MANUAL. - Page 10 7-3-1 Connection between 4–20 mA output type controller and instrument (4–20 mA input) To connect multiple units of the instrument, wire them in series as shown below. The input resistance of the instrument (4–20 mA input) is 100 Ω. Therefore, if the allowable load resistance range of the controller is 600 Ω, up to six units of the instrument can be connected.

Page 11: Wiring Of Alarm Circuit
7-3-5 Over-rise protection circuit (for voltage/current input type) This is a method of cutting off signals from the controller to stop control output. Cutting off the continuity between terminals 4 (VR1) and 6 (VR+) also causes the output to stop. 7-3-6 Over-rise protection circuit (for contact input type) In the following wiring diagram, an alarm contact is added to terminal 6 (VR+) to cause the circuit to open, to stop output when the over-rise prevention becomes active. -
Page 12: Output Adjustment Function
8. Output Adjustment Function 8-1. Power adjustment The power adjustment dial is used to control the output power of the PAC46 in the range of 0 to 100%. (Upper-left figure) For equipment that controls temperature by a heater etc. based on its output, you can use the power adjustment dial (variable resistor) to set the desired temperature. -
Page 13: External Power Adjustment
■ Comparison with program control Programmed control has characteristics such that it can prevent overshooting at the start time and handle temperature ramping at extremely low speeds. 8-3. External power adjustment External power adjustment is used to adjust the output of the instrument from a remote location. -
Page 14: Manual Power Adjustment
8-5. Manual power adjustment Manual power adjustment is generally used to adjust output without using control input (automatic mode), to carry out adjustment in a trial run, and to switch to the control input mode in selecting a manually-set output by means of external signals. An example of switching between automatic (control input) and manual modes and methods of adjustment are shown below. -
Page 15: High-Low Power Adjustment (When Combined With Contact Output Type Controller)
8-7. High-low power adjustment (when combined with contact output type controller) High-low power adjustment uses contact signals to adjust the power when the contact is short-circuited (high power) and when the contact is open (low power), for the enhancement of control efficiency. This adjustment method is also used when the heater characteristically requires current at a certain level to be supplied constantly. -
Page 16: Start-Up Time Output Limiting (Option)
8-9. Start-up time output limiting (option) This circuit can be used in two ways: • To limit output when power is supplied Use it by short-circuiting terminals 7 (DI-COM) and 9 (DI2). Care should be taken because turning the power on when terminals 7 (DI-COM) and 9 (DI2) are open results in a shortage of output, as the instrument continues to run with limited output. -
Page 17: Control Mode And Output Limiting Function
9. Control Mode and Output Limiting Function This instrument has various (voltage, current, power, and voltage square) feedback control modes. Feedback control functions to detect the output voltage or output current of the power regulator, and control it to an output value proportional to the control input. -
Page 18: Heater Break Alarm And Rapid Fuses
10. Heater Break Alarm and Rapid Fuses 10-1. Heater break alarm The instrument can be set to generate a heater break alarm by detecting a change in resistance value if it rises abnormally due a heater break or deterioration. However, this alarm may not function normally for heaters whose resistance value changes due to a temperature rise. Note 7: This function determines the presence of a heater break by calculating the approximate combined load resistance value between each phase. -
