■Noise generating sources and countermeasures

•Generally, the following generate electrical noise:

(1)Relays and contacts

(2)Solenoid coils, solenoid valves

(3)Power lines (in particular, 90Vac min.)

(4)Induction loads

(5)Inverters

(6)Motor commutators

(7)Phase angle control SCR

(8)Wireless communications equipment

(9)Welding equipment

(10)High-voltage ignition equipment

•If the influence of electrical noise cannot be eliminated, we recommend taking the following countermeasures:

- Provision of a CR filters for fast-rising noise Recommended CR filter: Model No. 81446365-001

- Provision of a varister for noise with a high wave height Recommended varister: Model No. 81446366-001 (100V)

81446367-001 (200V)

Handling Precautions

The varister may become short-circuited when trouble occurs. Pay attention to this when providing a varister on a controller.

■Dust-proof cover

Use the dust-proof cover when using the controller in a dusty or dirty location, and to prevent inadvertent operation.

Two dust proof-covers are provided, hard or soft, each with the following differing func- tions.

Type	Confirmation on Display Operation
