Operation Indicator-equipped Models (Not Approved by UL, CSA, or EN)

• All the models can be equipped upon request with a operation indicator to facilitate maintenance and inspection.

• Because the indicator is incorporated in the Terminal Protective Cover, the dimensions of the Limit Switch are not affected. In this model, the

lead wire is to be connected to the screw terminal. (A connecting washer is provided on the tip of the lead wire).

The lead wire can be connected to either the NC or NO terminal.

• Operating characteristics are the same as the standard model from which the operation indicator equipped model is fabricated.

(For AC)

• The operating voltage range is from 90 to 250 VAC.

• The dimensions are the same as the standard type. The top of the

Terminal Protective Cover is transparent to allow checking the

operation easily.

• When placing your order for the indicator equipped, AC-operated

model, add suffix "L" to the end of the model number.

Example:

Standard type:

ZC-Q2255

Indicator equipped type: ZC-Q2255-L

Contact Circuit

Note: If the wiring is as shown above, the operation of the respective parts will

be as shown in the following table. The neon lamp is not wired when the

Switch is delivered. Connect it as required.

(For DC)

• The DC-operated is provided with an LED indicator.

• There is no protective structure.

• Since a rectifier stack is incorporated into the unit to permit reversing

the polarity, this type can also operate on AC power source.

• The LED projects from the housing for easy visibility.

• When placing your order, add suffix "L2" or "L4" to the model number of the standard type.

Example:

Standard type:

ZC-Q2255

Indicator equipped type: ZC-Q2255-L2

Contact Circuit

Note: If the wiring is as shown above, the operation of the respective parts will

be as shown in the following table. The LED terminals are not wired when

the Switch is delivered. Connect it as required.
