Testomat 2000 CLF

Summary

Product Identification

• Product Name: Testomat 2000® CL T, Testomat 2000® CL F
• Type: Process Photometer for total chlorine (CL T) or free chlorine (CL F)

Operating Limits

• Total Chlorine Measuring Range: 0 – 2.5 ppm
• Free Chlorine Measuring Range: 0 – 2.5 ppm
• Operating Pressure Range: 0.3 to 8 bar (with flow controller valve body removed for 0.3 to 1 bar range)
• Measuring Water Temperature: 10 °C to 40 °C (for temperatures above 40 °C, a KCN type cooler is recommended)

Feed Water

• Requirements: Must be clear, colourless, and free of undissolved particles.
• Maximum CO₂ Concentration: Incorrect evaluations may occur if CO₂ concentration exceeds 20 mg/l.

Product Water

• Analysis Principle: Wet-chemical online monitor using the photometric analysis principle, based on the DPD method according to EN ISO 7393-2.
• Measurement Time: Approximately 1 minute reaction time, plus analysis and flush times.
• Reagents: Requires specific Heyl Testomat 2000® reagents (A and B for free chlorine; A, B, and C for total chlorine).

Electrical

• Power Supply: Requires an interference-free and stable power supply. Mains voltage specified on the rating plate (e.g., 24 V / 115 V / 230 V).
• Relay Outputs: Max. 240 VAC, 4 A. Used for:
  • External flush valve (Flush OUT)
  • Limit value output 1 (LV1 OUT)
  • Limit value output 2 (LV2 OUT)
  • Measuring point switch-over (M. point. 1/2 OUT)
  • Universal output (AUX OUT)
  • Fault message output (Alarm OUT)
  • Maintenance message output (Maintenance OUT)
• Inputs:
  • External analysis start (Start IN)
  • External analysis stop (Stop IN)
  • Universal input 1 (IN1 IN)
  • Universal input 2 / water meter (IN2 IN)
• Optional Interface: 0/4-20 mA or 0/2-10 V, or RS 232 for log printer.

Mechanical / Hydraulic

• Water Inlet Connection: Standard plug connector for plastic hoses 6/4 x 1 (6 mm outer diameter / 4 mm inner diameter). Maximum inlet hose length of 5 m recommended.
• Water Outlet Connection: Requires an opaque outlet hose with an internal diameter of 14 mm. Hose must be laid without backwater or siphoning effect.
• Reagent Storage: 500 ml reagent bottles.
• Internal Design: Includes terminal strips, mains switch, dosing pump, controller/filter receiver, and measuring chamber.

Operation

• Modes: Time control, quantity control via water meter, dynamic analysis start, and external analysis start.
• Analysis Interval: Programmable from 0 to 99 minutes.
• Limit Value Monitoring: Two independent limit values (LV1, LV2) with programmable hysteresis (1, 2, or 3 bad analyses).
• Display: 4-line text display showing measured values, statuses, and programming data. Includes status indicators for limit values, alarm, and maintenance.
• Reagent Handling: Requires careful insertion and extraction of reagents.
• Settings: Menu-driven operation via a keypad and display. Basic program requires a four-digit password (current time in reverse order).
