Selecting an Installation Site

Section 3-2

 

 

 

Momentary Power Failure Detection

A momentary power failure lasting less than 10 ms with an AC power supply and 2 ms with a DC power supply is not detected and the CPU Unit continues to oper- ate.

A momentary power failure lasting longer than 10 ms with an AC power supply and 2 ms with a DC power supply may or may not be detected in an uncertain area.

When a momentary power failure is detected, the CPU Unit stops operating and the output goes OFF.

Automatic Restart

When the supply voltage recovers to a value higher than 85% of the rated value, operations resumes automatically.

 

Under

Duration of power interrupt

 

 

 

 

 

 

 

(Below 85% of rated voltage)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Normal operation

 

 

 

 

 

Operation may stop.

 

 

 

 

 

All outputs go OFF when

operations stop.

Note The CPM1A may repeat stop/start operations if the supply voltage of less than 85% of the rated value gradually goes up or down.

If this affects the equipment, etc., provide a protection circuit which shuts off the output if the supply voltage is not above the rated value.

Time Up to the Start of Operation

The time from when the power supply is turned on to when the operation starts varies depending on the operation conditions such as power supply voltage, configuration, ambient temperature, etc. The minimum time is approximately 300 ms.

3-2 Selecting an Installation Site

The CPM1A is resistant to harsh conditions and highly reliable, but installing the

PC in a favorable site will maximize its reliability and operating lifetime.

!Caution Be sure to install the CPM1A correctly, as outlined in this manual. Failure to do so may result in Unit malfunction.

3-2-1 Installation Site Conditions

Note Do not install the CPM1A under any of the following conditions.

•Locations subject to direct sunlight.

•Locations subject to a temperature below 0° C or over 55° C.

•Locations subject to a humidity below 10% or over 90%.

•Locations subject to condensation as the result of severe changes in tempera- ture.

•Locations subject to corrosive or flammable gases.

•Locations subject to dust (especially iron dust) or salts.

•Locations subject to shock or vibration.

•Locations subject to exposure to water, oil, or chemicals.

Be sure that the conditions at the installation site conform to the CPM1A’s gen- eral specifications. Refer to 2-1-1 General Specifications for details.
