ASCO Solenoid Spool Valves and Azbil 100 Series Model AVP100 102 Smart Valve Positioner Valve Controller

Azbil's Smart Valve Positioner 100 Series (AVP100/102) is a microcontroller-based device that converts 4-20 mA DC input signals into pneumatic output to control valve position. The AVP100 is analog-only, while the AVP102 integrates HART6 protocol for bi-directional communication. It supports electrical adjustments for input-valve position relationships, including split-range and custom flow curves. Designed for single/double-acting actuators, it features auto-setup for actuator detection and calibration. The positioner includes a VTD sensor for feedback, EPM for electro-pneumatic conversion, and pilot relay for air amplification, ensuring precise control with diagnostics for reliability in industrial settings.

• Auto-Setup and Calibration: Switch-activated program detects actuator type and adjusts zero/span; manual zero/span via screwdriver.
• HART Integration (AVP102): Supports HART communicator or CFS100 software for configuration, dummy signals, and diagnostics like deviation alarm and temperature alarm.
• Control Configuration: PARAM settings for actuator size, hysteresis (LIGHT/MEDIUM/HEAVY), PID parameters for optimized response.
• Fail-Safe and Safety: Fail-safe position on critical failure, surge absorber, lightning protection (12 kV/1000 A), protective grounding <100 Ω.
• Maintenance Features: A/M switch for manual air bypass (single-acting), EPM balance adjustment, self-diagnostics for RAM/ROM/NVM errors.
• Block Diagram: Input conversion, PID calculation, EPM driver, pilot relay, VTD feedback; air supply 140-700 kPa for balanced operation.
• Reversing Relay for Double-Acting: Integrates for opposite pressure output, with OUT1 through SVP and OUT2 balance.

Optimized for precision valve positioning in process industries requiring robust performance, such as petrochemical refineries and power plants. Compatible with Azbil HA/PSA/VA actuators, Masoneilan, Fisher, and others for linear or rotary motion. Suitable for hazardous locations with flameproof approvals, supporting control loops in systems with high magnetic interference or vibration.

• What to do if VTD FAULT error? Check feedback lever within ±20° angle, VTD connector, input line; contact Azbil if persists.
• HI/LO EPM OUT error? Verify air supply, input >4 mA, A/M in Auto, clean nozzle/orifice, adjust EPM balance, test with varying input.
• OVER TEMP error? Check SVP temperature and relocate to cooler area.
• LO IIN error? Ensure input signal at least 3.85 mA.
• ACT ERR error? Increase air supply, verify 1-10 psig, signatore using ValVue, perform value signal.
