Features
•
Standard Q46H/63 analyzers have fully isolated inputs and outputs. Analog outputs are
additionally completely isolated from each other.
•
Available in either 90-260 VAC or 12-24 VDC power supply systems. All features remain the
same in both variations.
•
High accuracy, high sensitivity system, measures from 20 ppb to 200.0 ppm through 4 internal
automatic ranges. User ranges of 200.0 ppb, 2.000 ppm, 20.00 ppm, or 200.0 ppm.
•
Output Hold, Output Simulate, Output Alarm, and Output Delay Functions. All forced changes in
output condition include bumpless transfer to provide gradual return to on-line signal levels and to
avoid system control shocks on both analog outputs.
•
Three 6 amp SPDT relay outputs and two analog 4-20 mA outputs are standard. Software
settings for relay control include setpoint, deadband, phase, delay, and failsafe. An optional 3-
relay card, for 0-30 VDC signals, is available to bring the total to 6 relays.
•
Selectable PID controller on main analog output. PID controller can operate with instrument
configured as loop-power analyzer or as one of the two outputs on the AC powered instrument.
PID includes manual operation feature, and diagnostic “stuck-controller” timer feature for alarm
output of control problems.
•
Digital communication options for Profibus-DP, Modbus RTU. More versions pending. See Q46
Digital Communications Manual for Specifications.
•
Optional pH sensor feature enables active pH measurement with the Q46H/63 monitor. The pH
reading can also be sent to one of the analog outputs for complete pH and chlorine monitoring.
•
Two analog outputs may be configured to track chlorine and temperature, chlorine and chlorine,
or chlorine and pH. Both analog outputs can be individually programmed to fail to specific values.
An optional third analog output is available, providing separate outputs for chlorine, pH, and
temperature.
•
Selectable Output Fail Alarm feature allows system diagnostic failures to be sent to external
monitoring systems.
•
Large, high contrast, custom LCD display with LED back light provides excellent readability in any
light conditions. The secondary line of display utilizes 5x7 dot matrix characters for clear
message display. Two of four measured parameters may be on the display simultaneously.
•
Diagnostic messages provide a clear description of any problem with no confusing error codes to
look up. Messages are also included for diagnosing calibration problems.
•
Quick and easy one-point calibration method and sensor zero-cal. To provide
high accuracy, all
calibration methods include stability monitors that check temperature and main parameter stability
before accepting data.
•
High accuracy three-wire Pt100 temperature input. Temperature element can be user calibrated.
