Metex 2200C Conductivity Analyzer/Controller - Manual (Page 4)

Model 2200C Page 2
2.0 SPECIFICATIONS
DISPLAY:
4 digit LED, 1/2" high digits
MEASURING RANGES:
Eighteen ranges;
The range is set at the factory as ordered, but maybe
changed in the field to any other range through the
Utility Menu.
Temperature: 0°C to 100°C (32°F to 212°F)
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
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 LED indicate status of the control
relay 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 4-20 mA analog output can be
made to represent any segment of the measuring
scale. Minimum segment is 10% of full scale.
Output Hold: The analog outputs are automatically
placed on hold during calibration or other setup
operations.
Temperature Output: The 0-5 Vdc output can be
programmed to follow the process temperature or
conductivity.
TEMPERATURE COMPENSATION:
Automatic 0°C to 100°C (32°F to 212°F)
SYSTEM ERROR:
A LED indicates a system error. The alarm relay can
be programmed to activate upon system memory loss.
DIAGNOSTICS:
Invalid entries are identified by respective flashing
LEDs. When a system error is indicated, use the CALL
button to display STATUS, to determine the status
code.
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 relay, alarm
relay, analog outputs to be tested independently of the
process.
SAFETY AND SECURITY:
Non-volatile memory (EPROM)
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
