Environment andEnclosure

This equipment is intended for use in a Pollution

Degree 2 industrial environment, in overvoltage

Category II applications (as defined in IEC publication 60664–1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR

Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.

This equipment is supplied as “open type” equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present, and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosures. Also, see the appropriate sections in this publication, as well as the

Allen–Bradley publication 1770–4.1, (“Industrial

Automation Wiring and Grounding Guidelines”), for additional installation requirements pertaining to this equipment.

•

When not in use, keep modules in appropriate static–safe packaging.

Calculate Power

Requirements

Setting the Module

Operational Jumper

Your CFM module receives its power through the 1771 I/O chassis backplane from the chassis power supply. The maximum current drawn by the CFM module is 0.8A. Add this value to the requirements of all other modules in the I/O chassis to prevent overloading the chassis backplane and/or backplane power supply.

ATTENTION

!

When using a 1771-P7 or 1771-PS7 power supply to power an I/O chassis, you cannot place more than four CFM modules in this chassis. The interaction between the four CFM modules and the 1771-P7 or 1771-PS7 power supply (not 16A limit) prevents the power supply from powering up.

Configurable Flowmeter Module

Configure the Module

To configure the CFM module, you enter

BTW and BTR instructions into your ladder logic, then you enter data into the BTW instruction. This data should conform to the input device and specific application that you have chosen.

You can configure the module using I/O configuration software or by editing bits in the BTW instruction.

Input Capabilities

The CFM module accepts input for up to four channels

(mode dependent). Each of the four input channels may accept these input signals:

• magnetic pickup — 50mV to 30V ac

•

3-30V dc pulses with open collector (TTL compatible)

• proximity probe inputs

–

compatible with Bently Nevada 3300

(5mm and 8mm) proximity transducer systems

–

provides two isolated 24V dc power supplies

(rated at 12mA) to power external devices

During normal operation, the processor transfers 1 to 60 words to the CFM module when you program a BTW instruction to the

CFM module’s address.

IMPORTANT

You must program at least one

BTW, with a word length of 4, to get useful data back from the

CFM module.

Your PLC processor gets data from the

CFM module using BTR instructions in your ladder logic program. The CFM module transfers up to 41 words to the PLC processor’s data table file. The words contain module status and input data from each channel.

You should program a block transfer read length of zero (0). When a BTR of 0 is programmed, the CFM module will determine the correct number of words (41) to return.

Output Capabilities

The CFM module has four assignable outputs. These outputs are designed for applications that require fast response. The outputs:

• are electronically current limited to 2A

• can be assigned to any input channel with user-selectable turn-on and turn-off values

• are current sourcing at 5-30V dc (1A maximum per output)

• must be connected to an external power supply

• are in groups of two — this lets you use two separate external power supplies if desired (one for outputs 0&1 and one for outputs 2&3)

Outputs may be forced on or off independent of count or frequency value. They may be forced on and off by setting bits in the BTW configuration block.

IMPORTANT

You can assign as many as four outputs to a given channel; however, you can not use the same output with two different channels.
