Series 220/221 Instruction Manual Chapter 5 Troubleshooting & Repair
•
Pulse Out Queue = Pulse output queue. This value will ac-
cumulate if the totalizer is accumulating faster than the pulse
output hardware can function. The queue will allow the pulses
to “catch up” later if the flow rate decreases. A better practice
is to slow down the totalizer pulse by increasing the value in
the (unit)/pulse setting in the totalizer menu.
•
TOF, G, f = factory use only.
•
Sig. Rev = Signal board hardware and firmware revision.
•
Micro Rev = Microprocessor board hardware and firmware
revision.
•
AD, R, T, F, PT, V = factory use only.
•
SPI Err, Rcv, Sent = factory use only.
Column Two Hidden Diagnostics Values
• 4-20(1), Zero = Analog counts to calibrate zero on analog output.
• 4-20(1), FScale = Analog counts to calibrate full scale on analog
output.
• Vor Freq Direct? = Frequency output setting, used by factory dur-
ing calibration. Set to NO if totalizer is used.
• Reynolds Corr. = Reynolds number correction for the flow profile.
Set to Enable for series 221 insertion and set to Disable for series
220 inline.
• Gain Control = Manual gain control (factory use only). Leave set at
1.0.
• Filter control = Manual filter control. This value can be changed to
any number to force the fi value (which will be displayed as fm) to a
constant. A value of zero activates the automatic filter control which
sets fi at a level that floats above the f value.
• Factory Defaults = Reset to factory defaults. If you change this to
YES and press ENTER, all factory configuration is lost and you
must reconfigure the entire program. Consult the factory before per-
forming this process, it is required only in very rare cases.
• Meter Type = Insertion (model 221) or Inline (model 220) meter.
• Test Pulse Out = Force totalizer pulse. Set to YES and press
ENTER to send one pulse. Very useful to test totalizer counting
equipment.
Analog Output Calibration
To check the 4–20 mA circuit, connect a DVM in series with the output
loop. Select zero or full scale (from the second column of the hidden di-
