1. MOUNTING METHOD
Mounting
External receiving resistor
Note
Insert/pull out the main unit into/from the socket vertically to the face of socket. Otherwise the terminals are bent and it may cause a bad contact.
Wiring should be connected to the terminals on the socket of the product. The terminals for external connections are of M3 screws. Use crimp-on terminal lugs for connections to the terminals.
Recommended cables: A nominal cross-sectional area of
0.5 mm2 or thicker for signal cables, and that of 1.25 mm2 or thicker for power cables.
1.1 Wall Mounting
Loosen the main unit-xing screw of the product and pull out the main unit from the socket. Fix the socket on the wall with screws. Next, insert the main unit into the socket and fasten the main unit with the main unit-xing screw.
Main unit
1.2 DIN Rail Mounting
Insert a DIN rail into the upper part of the DIN rail groove on the rear of the socket, and then slide the slide lock at the lower part of the socket upwards until the socket is xed into position as shown below
1.3 Mounting Using
When using a multi-mounting base, see the User’s Manual for VJCE (VJCE Mounting Base).
1.4 Using a Duct
When using a wiring duct, install the duct at leaset 30 mm away from the top and bottom faces of the main unit.
2. INSTALLATION LOCATION
• Avoid the following environments for installation locations: Areas with vibration, corrosive gases, dust, water, oil, solvents, direct sunlight, radiation, a strong electric eld, and/or a strong magnetic eld, altitude of more than 2000m above sea level.
• If there is any risk of a surge being induced into the power line and/or signal lines due to lightning or other factors, a dedicated lightning arrester should be used as protection for both this converter and a eld-installed device.
• Operating temperature/humidity range: 0 to 50C/5 to 90%RH (no condensation)

Note
● Do not use output-2 for the single-output type.
● The power line and input/output signal lines should
be installed away from noise-generating sources. Other wise accuracy cannot be guaranteed.
● 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 (terminal no. 8) of the product to the ground. Do not carry out daisychained inter-ground terminal wiring
● Use of the product ignoring the specications may
cause overheating or damage. Before turning on the power, ensure the following:
Power supply voltage and input signal value applied to
The external wiring to the terminals and wiring to ground
● Do not operate the product in the presence of
ammable or explosive gases or vapors. To do so is highly dangerous.
● The product is sensitive to static electricity;
exercise care in operating it. Before you operate the product, touch a nearby metal part to discharge static electricity.
● For 15-30 V DC (±20%) power supply, as a safety
measure, always install a circuit breaker (an IEC 60947-compatible product, 1 A, 30 V DC) in an easily accessible location near the instrument. Moreover, provide indication that the switch is a device for turning off the power to the instrument.

2. For the high signal selector: VJSS-H□□-□□□0 Apply the input signal equivalent to -5 to 0% of the input span to one of two inputs of the converter from a voltage current source. For the low signal selector: VJSS-L □□ - □□□ 0 Apply the input signal equivalent to 100 to 105% of the input span to one of two inputs of the converter from a voltage current source.
3. Apply the input signal equivalent to 0, 25, 50, 75, and 100% of the input span to one of two inputs of the converter from a voltage current source.
4. Check to see the corresponding output voltages are 0, 25, 50, 75, and 100% respectively and within the specied accuracy rating. “R” is used for current output.
• Use the setting tool (VJ77 Parameter Setting Tool or JHT200 Handy Terminal) to adjust the input/output signals.
Input Adjustment Procedure
(1) Input the value equivalent to 0% value of the input range to
the high/low signal selector.
(2) Call the display item (A: DISPLAY1) to check the input value
in A01: INPUT1.
(3) If the adjustment is necessary, call the adjustment item (P:
ADJUST).
(4) Select P08: IN1 ZERO ADJ to enter the adjustment mode.
Select EXECUTE (adjustment) for adjustment. (If RESET is selected, the adjusted value is reset to the factory-set default.)
(5) Input the value equivalent to 100% value of input range. (6) Call the display item (A: DISPLAY1) to check the input value
in A01: INPUT1.
(7) If the adjustment is necessary, call the adjustment item (P:
ADJUST).
(8) Select P09: IN1 SPAN ADJ to enter the adjustment mode.
Select EXECUTE (adjustment) for adjustment. (If RESET is selected, the adjusted value is reset to the factory-set default.)
• Input-2 can be adjusted by the same operation as the above.

Output Adjustment Procedure
(1) When adjusting 0% value of output, call the adjustment item
(P:ADJUST) to select [P26:OUT1ZERO ADJ].
(2) If there is a positive deviation, correct it by setting a negative
value to offset the deviation. If there is a negative deviation, correct it by setting a positive value.
*: The 100% value of output-1 and the 0%/100% value of
output-2 can be adjusted by the same operation as the above. For adjustment using a setting tool, refer to the User’s Manual for each setting tool and “6. LIST OF PARAMETERS” in this manual. User’s Manual for VJ77 [Document No.: IM 77J01J77-01E]; however, use the VJ77 of version R1.04 or later. User’s Manual for JHT200 [Document No.: IM JF81-02E]
