Cautions when Attaching to the Panels
•
Please attach the PXG5/PXG9 with the included fixtures (2 pieces) to the top and bottom,
and tighten with a screwdriver.
The clamp torque is approximately 0.15 N/m (1.5 kg/cm)
•
It is designed such that overtightening will cause left/right cracking to the central area of
the Fixtures and hence reduce the torque.
Cracking to the central area will not cause any problems in terms of usability of the equip-
ment.
(However, do exercise caution in not applying too much torque because the casing is
made of plastic.)
•
The front of this equipment is waterproof in compliance with NEMA-4X standards (IP66-
equivalent).
To effect waterproof, the included packing is shall be attached between the controller and
the panel according to the guidelines below. (Incorrect attachment may cause the equip-
ment to lose its waterproof capabilities.)
(1) As shown in Fig. 1, insert to the panel after attaching the packing to the equipment
case.
(2) As shown in Fig. 2, tighten the fixture screws so that no gaps can remain between the
equipment face, the packing and the panels. Once finished, confirm that there are no
changes in shape such as displaced or improperly-fitted packing, etc. as shown in
Fig. 3.
If the panel does not have enough strength, gaps may develop between the packing and
•
the panel to lose waterproofing capabilities.

If attached at an angle, the maximum
gradient is a 30° downslope.
In order to aid heat dissipation, do not block the sides of the equipment.
•
Caution
Do not block the air vents on the upper part of the terminal.

•
For the PXG9, please attach the fixtures to the attachment holes in the
center of the main unit.
Cautions for Wiring
2-3
For thermocouple input, use the designated compensation lead; for resistance bulb input,
•
use wires with small lead wire resistance and without any resistance difference among the
three wires.
•
To avoid noise conductor effects, input signal wires should be separated from electric
power lines or load lines.
Input signal wire and output signal wire should be separated each other. And both should be shield
•
wire.
•
If there is a lot of noise from the power source, adding an insulation transducer and using a
noise filter is recommended.
(Example: ZMB22R5-11, noise filter Maker: TDK)
Always attach a noise filter to a panel that is grounded securely, and keep the wiring
between the noise filter output side and the measuring equipment power terminal wiring
to a minimum length.
Please do not attach fuses and switches, etc. to the noise filter output wiring, otherwise the
filter's effectiveness will be decreased.
Twisting the power wires is effective when connecting the wires. (The shorter the pitch of
•
the twist, the more effective the connection is against noise.)
•
If there is a function of heater current detection, heater wires and power wires should be
connected with same power line.
Operation preparation time is required for the contact output when power is turned on. If
•
using it as a signal to an external interlock circuit, please couple it with a delayed relay.
•
Concerning the output relay, connecting the maximum rated load will shorten the prod-
uct's life; so please attach an auxiliary relay. If the output operation frequency is high,
selecting a SSR/SSC drive output type is recommended.
[Proportionate cycles] Relay output: 30 seconds or more, SSR/SSC drive output: 1
•
When inductive loads such as magnetic opening/closing equip-
ment, etc. as relay output equipment are connected, use of
"Z-trap," manufactured by Fuji Electric Device Technology Co.,
Ltd., is recommended in order to protect the contacts against
opening/closing surges and to ensure long-term use.
Model names :
ENC241D-07A
(For 100V power voltage)
ENC471D-07A
(For 200V power voltage)
Attachment position : Please connect between the relay
control output contacts.

Key Operation Caution/Error Operation
The alarm function does not work properly when an error takes place unless the settings
•
are made correctly. Always verify its setting before operation.
If the input wiring breaks, the display will read "
•
turn the power OFF.

Others
•
Please do not wipe the equipment with organic solvents such as alcohol or benzene, etc.
If wiping is necessary, use a neutral cleaning agent.
Do not use mobile phones near this equipment (within 50 cm). Otherwise a malfunction
•
may result.
•
Trouble may occur if the equipment is used near a radio, TV, or wireless device.
