For example, inrush current can be reduced at startup by selecting soft-start optimum cycle control if a single-phase halogen heater is used. The Control Switching MV Threshold function is enabled when softstart optimum cycle control is used. Setting the Control Switching MV Threshold enables switching to soft-start control when the current value is below the set value, and switching to optimum cycle control when the current value is above the set value. The default setting is 20.0%. SSR Control method CT (4-channel models only) Example of supported heater Single-phase Optimum cycle 0 to 50 A or 0 heater SSR with control to 150 A: 4 zero-cross function Units SIngle-phase heater Single-phase Soft-start 0 to 50 A or 0 heater SSR without optimum cycle to 150 A: 4 zero-cross function control Units Single-phase halogen heater Three-phase Three-phase 0 to 50 A or 0 Three-phase heater SSR with optimum cycle to 150 A: up to heater zero-cross function control 2 Units Optimum Cycle Control • Optimum cycle control is performed by driving SSRs according to load power detection and trigger signals. (Zero-cross SSRs are used.) • Noise is suppressed while ensure high-speed response by turning outputs ON and OFF each half cycle to achieve high-precision temperature control. 1/5th ON (20%) Control Capacity: 20% Variable type 85/C5 Parameter Setting range Ch1 to Ch8 Control Switching MV Threshold 0.0% to 100.0% Default 20.0 Example: For channel 1, soft-start optimum cycle control is performed under the following conditions: control switching MV: 40.0%, MV: 100.%, soft startup time: 20 s. (1) Ch 1 Control Switching MV Threshold is set to 40.0% and Ch1 MV is set to 100.0% by writing to the variable area. (2) Ch1 Soft Startup Time remains at the default. Setting is not required. (3) Once the Control Switching MV Threshold is written, the changes are saved and become enabled the next time the power is turned ON. MV/Control Capacity 100.0% 40.0% Note: Refer to Connection Configuration on page 6 for connecting to an SSR. Time Soft startup time (20 s) Soft-start Optimum Cycle Control • Soft-start and optimum cycle control enables control of outputs with limited inrush current even for loads with characteristics like halogen heaters. • Use a single-phase heater SSR (without the zero-cross function) for soft-start optimum cycle control. Refer to G3PA for details on SSRs without the zero-cross function. • Set the Soft-start Up/Down Time to control output. • Current is not detected during Soft-start. The current value (heater ON current value, heater OFF current value, and effective current value) will be 0 A, and the current error alarm (heater burnout detection, SSR short-circuit detection, and heater overcurrent detection) will always turn OFF. Soft-start Optimum cycle control Three-phase Optimum Cycle Control • Three-phase optimum cycle control is a control method that turns the output ON and OFF every two cycles. • Turning the output ON and OFF every two cycles enables optimum cycle control for three-phase heaters. • Use a three-phase heater SSR with a zero-cross function for threephase optimum cycle control. Note: Refer to page 6 for details on connecting to three-phase heaters. The following figure shows the current waveform of each phase for a Control Capacity of 50% when a three-phase heater SSR is connected.

Doing so may possibly result in electric shock. Make sure that the terminal cover is installed before using the product. !CAUTION Do not allow pieces of metal, wire clippings, or fine metallic chips or filings from installation to enter the product. Doing so may occasionally result in electric shock, fire, or malfunction. Do not use the product in locations of flammable or explosive gases. Doing so may occasionally result in minor or moderate explosion, causing minor or moderate injury, or property damage. Do not attempt to disassemble, repair, or modify the product. Doing so may occasionally result in minor or moderate injury due to electric shock. Perform correct setting of the product according to the application. Failure to do so may occasionally cause unexpected operation, resulting in minor or moderate injury, or damage to the equipment. Ensure safety in the event of product failure by taking safety measures, such as installing a separate monitoring system to provide alarms for preventing excessive temperature rise. Product failure may occasionally prevent control operation, resulting in damage to the connected facilities and equipment. Tighten the terminal screws securely using a tightening torque within the following ranges. Loose screws may occasionally cause fire, resulting in minor or moderate injury, or damage to the equipment. Terminal screws: 0.40 to 0.56 N·m 10.Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors, transformers, solenoids, magnetic coils, or other devices that have an inductance component). Do not install the product near devices generating strong highfrequency fields or surges. When using a noise filter, check the voltage and current and install it as close to the product as possible. 11.For a safety disconnection of the power-line in the application, the equipment must be provided with disconnecting devices suitable for isolation. (e.g., circuit breakers defined in IEC60947-2, power switches defined in IEC60947-3, power plugs, etc.) Version 1.0 Usage Precautions Version 1.0 is for single-phase loads only. Connect a single-phase zero-cross SSR. Do not connect a three-phase SSR, or to an SSR that is not magnet relay or zero-cross. Version 2.0 Usage Precautions • Check the G3ZA settings and select the correct SSR from the following when wiring an SSR. • SSR with zero-cross function for single-phase heaters • SSR without zero-cross function for single-phase heaters • Three-phase SSR Do not connect a magnet relay. • Check the G3ZA settings and select the correct CT from the following when wiring a CT. • E54-CT1 • E54-CT3 • G3ZA-CT150L ■ Precautions for Safe Use 1. Do not use the product in the following locations. • Locations subject to direct radiant heat from heating equipment • Locations where the product may come into contact with water or oil • Locations subject to direct sunlight • Locations where dust or corrosive gases (in particular, sulfuric or ammonia gas) are present • Locations subject to extreme temperature changes • Locations where icing or condensation may occur • Locations subject to excessive shocks or vibration 2. Use this product within the rated load and power supply. 3. Ensure that the rated voltage is achieved no longer than 2 s after turning the power ON. 4. Use/store within the rated temperature and humidity ranges. 5. Minimum mounting distance of G3ZA is 10 mm. When mounting the G3ZA near the SSRs, mount the G3ZA so as to not interfere with the heat dissipation of the SSR. 6. Use the specified size of insulated-type crimp terminals (M3, width: 5.8 mm max.) for wiring and attach insulative sleeves. To connect bare wires, use AWG22 (cross section: 0.326 mm2) to AWG14 (cross section: 2.081 mm2) to wire the power supply terminals and AWG22 (cross section: 0.326 mm2) to AWG16 (cross section: 1.039 mm2) for other terminals. 7. Be sure to confirm the correct terminal and polarity when wiring the terminal block and connectors. 8. Do not connect any conductors to unused terminals. 9. In order to prevent inductive noise, wire the lines connected to the product separately from power lines carrying high voltages or currents. Do not wire in parallel with or in the same cable as power lines. Other measures for reducing noise include running lines along separate ducts and using shield lines. 9 G3ZA ■ Precautions for Correct Use Mounting End Plates Be sure to mount an End Plate on each side of the G3ZA so that it does not slide on the DIN Track. Wiring Use M3 crimp terminals. 5.8 mm max. To mount an End Plate, hook the bottom of the End Plate on the bottom of the DIN Track (1), place the top of the End Plate on the DIN Track (2), and then pull down on the End Plate. Tighten the screw on the End Plate to secure it. (2) 5.8 mm max. Use wires that withstand a minimum of 70°C.

Installation Example When installing the SSRs next to the G3ZA, provide sufficient space between the G3ZA and SSRs, as shown in the following diagram. Reference example: When applying 25 A to the G3PE-225B (a manipulated variable of 100%), separate the SSRs from the G3ZA by at least 50 mm. Mounting the G3ZA Do not touch the G3ZA while power is being supplied. Mount the G3ZA as shown in the diagram. First, pull down the DIN Track mounting hook (1) and hook the top of the G3ZA on the DIN Track (2). Then press the G3ZA onto the DIN Track far enough so that it can be locked in place (3) and push the DIN Track mounting hook up to lock the G3ZA in place (4).
