Aquametrix 2200R ORP Analyzer/Controller User Manual - Manual (Page 4)

Model 2200R Page 2
2.0 SPECIFICATIONS
DISPLAY:
4 x 7 segment ½” LED Display
MEASURING RANGES:
ORP: 0 to 1000mV or -1000mV to +1000mV
POWER REQUIREMENTS:
Standard: 98-132 Vac, 50/60 Hz (less than 5 VA)
Optional: 196-264 Vac, 50/60 Hz (less than 5 VA)
23-26Vdc (nominal current 150mA)
AMBIENT CONDITIONS:
-30 to 50°C (-22 to 122°F)
0 to 90% R.H. non-condensing
CONTROL RELAY:
5A 115/230 Vac, 5A 30 Vdc SPDT
Selectable to activate in response to rising or falling
process
Fully adjustable setpoint and deadband
Manual Override Auto / Off / On for Relay A
Cycling Feature: On time 0-600sec Off time 0-600sec
Normal or Fail Safe operation
ALARM RELAY:
5A 115/230 Vac, 5A 30 Vdc SPDT
Programmable to activate at high and low alarm
setpoints
Deadband fixed at 2% of Full Scale
Normal or Fail Safe Operation
RELAY INDICATORS:
Three individual LEDs indicate status of the two
control relays and the alarm relay.
ANALOG OUTPUTS:
Non Isolated 0-1mA, 100 ohms maximum load
Non Isolated 0-5Vdc, 1000 ohms minimum load
Isolated 4-20mA, 800 ohms maximum load
Range Expand: The analog outputs can be scaled to
represent any segment of the full scale of the
instrument. Minimum segment is 10% of Full Scale.
Output Hold: The analog outputs are automatically
placed on hold when the unit is placed in any menu
mode.
SENSOR-TO-ANALYZER DISTANCE:
Differential Probe (R60) 3000 feet maximum
Conventional combination probe 25 feet (an
AquaMetrix Series 101 preamplifier is required for
distances greater than 25 feet)
CALIBRATION:
Two point
TEMPERATURE READOUT:
Automatic 0°C to 100°C (32°F to 212°F) If probe has
temperature compensation
SYSTEM ERROR:
A LED indicates a system alarm. The alarm relay can
be programmed to activate upon system memory loss.
DIAGNOSTICS:
Invalid entries are identified by respective flashing
LEDs. When a status error occurs, press CALL to
obtain the status error number, which corresponds to a
fault as described in the Status Fault Table.
TEST:
Display value and analog outputs can be set manually
to any value for testing and diagnostic purposes. This
feature allows the operation of the control relays,
alarm relay, and outputs to be tested independently of
process value.
SAFETY AND SECURITY:
Non-volatile memory (EEPROM)
Password protected if enabled
Watch-dog timer monitors microprocessor
Instrument automatically returns to on line operation if
accidentally left in menu mode. (This feature may be
field disabled if desired.)
SENSITIVITY: 0.1% of span
STABILITY: 0.1% of span per 24 hrs. non-cumulative.
NON-LINEARITY: 0.1% of span
REPEATABILITY: 0.1% of span or better
TEMPERATURE DRIFT:
Zero: 0.01% of span per °C
Span: 0.01% of span per °C
RESPONSE TIME:
0.5 second to 90% of value upon step change

enclosure with four 1/2" conduit holes and mounting
feet for surface mount. A NEMA 4 plug is provided for
one hole.
