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.
