CAUTION
●
Do not use output-2 for the isolated 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.
●
Make sure to earth ground the ground terminal
through minimum resistance. 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 daisy-
chained inter-ground terminal wiring.
●
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.
●
The use of inductance (L) loads such as auxiliary
relays and solenoid valves causes malfunction or
relay failure; always insert a CR filter or diode for
spark-removal into the line in parallel with the load.
Recommended CR
• C: 0.5 to 1µF against contact current 1A
•
R: 0.5 to 1Ω against contact voltage 1V
●
If the ambient temperature is 50 °C or more, please
use the cable that the rated temperature is 70 °C or
more.
4. DESCRIPTION OF FRONT PANEL AND
CONNECTION OF HANDY TERMINAL
4.1 Front Panel
The communications connector in the front panel is used for
setting up parameters through the PC (VJ77 Parameters Setting
Tool). The alarm-1 and alarm-2 LEDs light up if an alarm occurs
(those LEDs are provided only when the output-2 is specified for
alarm output (the output-2 suffix code is T).)
