The Prover Simulator Board simulates the operation of a Bi-directional, Uni-directional or Compact Prover. When in Bi- or Uni-directional mode, there are two prover volumes simulated. In the Compact Prover mode, the volume detect switch output is an open-collector output. The board is configured using the User Interface Board to enter the Prover Type (Bi-, Uni- or Compact), Volume 1 Pulses, Volume 2 Pulses and the Fourway Transition Time (Time to go from Reverse to Forward position and vice versa). Other features include:
- DIN Rail mounting
- 24 VDC operation
- All connections via plug and header, not terminals
- Compatible with either Sourcing (24 VDC) or Sinking (0 VDC) Fourway or Launch Commands
- Fourway Status and Volume Detect Switches can be configured to be High or Low Active
- Analog Output for Fourway (or Transfer) Valve seal (4.00 mA = No Seal; 18.80 mA = Seal)
- Launch Chamber Detect switches included
- Status for Fourway Valve includes Open Limit Switch, Close Limit Switch, Local/Remote Status and Seal (Differential Pressure Switch)
- SPST relays installed for Valve Status and Volume Detect Switches
- Program Reset button included for initial wiring checkout. Connections provided for remotely operated switch (dry contacts) for convenience
- LEDs indicate Forward (Launch) and Reverse Commands
- LEDs indicate Valve Status
- LEDs included for each Volume Detect Switch
- LED indicates when meter pulses are being received
- LED included for open-collector (Compact Prover) Volume Detect Switch
- LED flashes two times per second when CPU is operating correctly
- Prover Type, Pulses per Prover Volume and Fourway or Transfer Valve timing configured through User Interface Board. Configured values are stored locally in EEPROM
- RS-232 interface to User Interface Board via Ethernet-type connector. If the cable supplied with the User Interface fails of is lost, a replacement can be obtained locally.
- Sixteen position rotary switch provided to generate errors and faults (Valve Failure, Seal Fail, Detect Switch Fail, etc.)
