3.3. Pulse Output The pulse output circuitry for CAT2 is located on PCA180. The pulse output is scalable by a factor of 1, 2, 4, 8, 16 and 32 of the input frequency by selecting the proper switch on SW2. Scaling of the pulse output may be limited if an analog output is used in conjunction with the pulse output. - Page 19 Installation Open Collector, Isolated Pulse USER DCS SIG+ SIG- 2.7K ANLG PULSE PULSE+ INPUT PULSE- PCA180 PCA180 Open Collector Isolated Pulse HP-311...

Page 20: Analog Output
COURSE SPAN and FINE SPAN adjusts the max flow output. All pots are labeled accordingly on the circuit board and may be accessed by removing the top plate from CAT2. The 0-20mA, 0-5V and 0-10V options require no ZERO adjustment. Contact the factory for detailed calibration instructions before making any adjustments. -
Page 21: Alarm Outputs
Installation 3.5. Alarm Outputs CAT2 provides an optional High/Low Flow Alarm feature. The Alarms require an optional circuit board, PCA184. The Alarm option is not available when the AC Power option is equipped. The following drawings illustrate typical connections and switch settings for various alarm output options. -
Page 22: Wiring Note
When installing CAT2, it is a good practice to use shielded cables for all input and output signals. The shield should be connected to the earth ground lug on the CAT2. The shield on the opposite end of the cable should be left open.
