Installation
This chapter describes how to install a 1442 Series Eddy Current Probe System.
ATTENTION: Always ground the system. Never apply power until all
wiring work and connection work has been completed. If this is not
followed, there is a possibility of electrocution.
Installation work, wiring, and connections must be performed by a person
with knowledge in instrumentation.
ATTENTION: Be sure to adhere to the following guidelines:
• Before touching this unit, be sure to touch a metal section near by to
discharge any static electricity. The device can be damaged if exposed to
static electricity from a person’s body.
• Before applying power, make sure that all wiring is properly connected.
There is a possibility of damage to the unit and fire if improperly
connected.
• Install this unit away from motors and relays.
• Install the input/output signal cables away from power system and
control system cables. Noise occurring from the motor or relay can
adversely affect the measurement value. We recommend using separate
wiring ducts.
• Do not pull or bend the sensor cables and extension cables with
excessive force. The conductor in the cable can get cut off.
• The allowable tension of the sensor cables and extension cables is
98.1 N•m (10 kgf•m). The allowable bend radius is as follows:
– Without armored cable: 30 mm (1.18 in.)
– With armored cable: 50 mm (1.97 in.)
• After completing the installation, make sure all connections are correct
and tight before powering the system.
TIP
Refer to Appendix A on page 51 for recommended cable wiring, and
installation methods.
