3.2 Condition of Installation

NOTE
(1) Secure space for top and bottom to avoid
heating.
Apart more than 100 mm from the floor
board.
Apart more than 100 mm from panel top
and make air exhaust hole or set cooling
fan at panel upper.
If wall stands at back in case of rack
mounting, apart more than 60mm from the
wall for ventilation.
(2) Take enough space for front and side faces
so as not to interfere wiring, piping and maintenance area.
(3) In case storing in cabinet, air cooling is
compulsorily required to prevent from raise of
temperature. (4) Do not install it on the heating materials. (5) In case of installing the VJCE-01A one above
another to up and down direction, take
installation space as shown in the figure on
the right. (78 mm for rack mounting, 128 mm
for wall mounting)

3.3 Installation

3.3.1 Installation of VJCE-01A
Use four (4) M5 screws for installation.
3.3.2 Installation of signal conditioners
Connect the pin on the back of the signal conditioner to the VJCE-01A connector as shown in the figure on the right. Then tighten the fixing screw on the front of the signal conditioner.
NOTE
Insert and pull out the signal conditioner vertically to VJCE. Inserting and pulling it out slantwise may make the pin bent and cause a failure such as a bad contact.
IMPORTANT
Only one VJET can be mounted in slot 16 of VJCE­01A. Do not mount it in other slots.

4.2 Field Side Input/Output Terminals, Piping and System Side Wiring

Assignment of Input/Output Terminals on and after page 7 shows relation between VJCE-01A field side input/output terminals and signal conditioner input /output signal at the terminals. Field side input/output terminals are M3.5 screws. Connect input air pressure signal of VJF1 to connecting hole of front face of signal conditioner directly. Connect power and ground cables to power terminals of VJCE-01A. Power would internally be distributed to respec­tive signal conditioners.
WARNING
It is recommended that CT protector (CTG-5) be attached to the current input terminals connected to the secondary side of the CT when mouning VJB1 (CT transmitter) on VJCE-01A. Since a high potential develops over the secondary side, the CT may burn and break if you unplug the VJB1 from the VJCE­01A while the VJB1 is turned on and it has no CT protector.
IMPORTANT
Ensure the followings before turning on the power. Use of signal conditioners of VJ series ignoring the specifications may cause overheating or damage to VJCE-01A and signal conditioners.
· Power supply voltage and input signal value applied to VJCE-01A and signal conditioners should meet the required specifications.
· The external wiring to the terminals is as specifications.
Do not operate the product in the presece of flammable or explosive gases or vapors. To do so is highly dangerous.
Many semi-conductor integrated circuit parts are used for signal conditioners. Take care of static electricity trouble at the maintenance or change of setting for the signal conditioners.
The grounding resistance must be 100 Ω (JIS Class D grounding). The length and thickness of the grounding cable should be as short and thick as possible. Directly connect the lead from the ground terminal of the product to the ground. Do not carry out daisy-chained inter-ground terminal wiring.
