Applicable SSR and Control Methods
The G3ZA can be used for a variety of applications by selecting the
SSR drive. For example, inrush current can be reduced at startup by
selecting soft-start optimum cycle control if a single-phase halogen
heater is used.
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.
Note: Refer to Connection Configuration on page 6 for connecting to
an SSR.
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 halo-
gen 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.
Setting the Control Switching MV Threshold
The Control Switching MV Threshold function is enabled when soft-
start 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%.
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.
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 three-
phase 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.

can identify the Controller.
Note: A unique unit number must be set for each node (Controller) on
the same communications line. Do not set the same unit
number for more than one node.
If 17 or more Units must be connected, refer to the G3ZA Multi-

Safety Precautions
Refer to Safety Precautions for All Power Controllers.
!WARNING
!CAUTION
■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.
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 high-
frequency 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.

■Precautions for Correct Use
Wiring
Use M3 crimp terminals.
Use wires that withstand a minimum of 70°C.
DIN Track
Secure the DIN Track with screws in at least three locations.
DIN Track: PFP-50N (50 cm)/PFP-100N (100 cm)
Mounting the G3ZA
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).
Removing the G3ZA
Use a flat-blade screwdriver to pull down the DIN Track mounting
hook (1) and then pull out on the bottom of the G3ZA (2).
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.
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.
Note: Always mount one End Plate on each side of the G3ZA.
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.
Do not touch the G3ZA while power is being supplied.
