信號敏感度
高靈敏性可能更易受噪音損壞。
提高敏感度：順時針轉動信號電位計的敏感性 ( 圖4-12)。在順時針方向旋轉充分后，敏感度是大約為5 mVrms。
降低敏感度：逆時針轉動信號電位計的敏感性 ( 圖4-12)。在逆時針方向旋轉充分后，敏感度是大約為100 mVrms。
降低閉合觸點敏感度
跨接線終端30 和11能降低裝置的敏感度到大約1 Vrms。信號敏感度旋鈕不影響程序操作；

Changing the full-scale input frequency range
You can set the standard full-scale frequency range from as low as 0-80 Hz to as high as 0-20 kHz.
1 Remove the top plate from the SST-2000A/H to reveal the "A" DIP
switches.
2 Use Table 4-1, page 23, or the underside of the top plate (bottom of
Fig. 4-9, page 22) to determine the correct DIP switch settings.
3 Calibrate the SST-2000A/H using the procedure on page 22.
Input frequency range less than 80 Hz full-scale
The full-scale frequency input range is usually set up at the factory when an SST-2000A/H is ordered.
The SST-2000A/H can easily be field-modified for any standard full scale input frequency range from 0-80 Hz to 0-20,000 Hz using the procedure Recalibration
of Full-Scale Input Frequency Range.
Field-changing the SST-2000A/H to accept input frequencies less than 0-80 Hz full-scale is not recommended. Damage might result that could void the product
warranty.
Please contact the Dynalco Customer Service Department at (954) 739-4300 for guidance in arranging for a low input frequency range.
Input frequency range greater than 20,000 Hz full-scale
The full-scale frequency input range is usually set up at the factory when an SST-2000A/H is ordered.
The SST-2000A/H can easily be field-modified for any standard full scale input frequency range from 0-80 Hz to 0-20,000 Hz using the procedure Recalibration
of Full-Scale Input Frequency Range.
Field-changing the SST-2000A/H to accept input frequencies greater than 0-20,000 Hz full-scale is not recommended. Damage might result that could void the
product warranty.
Please contact the Dynalco Customer Service Department at (954) 739-4300 for guidance in arranging for a high input frequency range.
Chapter 4
Calibrating the SST-2000A/H
Calibrate the speed switch:
• immediately after any contact change in Switch A
• before adjusting set points or proportional output
You must calibrate the SST-2000A/H if you have made a change in the full-scale frequency range (changed contacts to DIP switch A).
1 Disconnect any meter connected to terminals 7 & 8. Mark or
position the wires so they can be correctly reattached later.
2 Connect a digital voltmeter across terminals 7(-) & 8 (+).
3 Connect a frequency generator (e.g. F-16) at terminals 5 (HI) & 6
(COM). Use the frequency generator to input the new full-scale
frequency.
4 Adjust the FREQ RANGE TRIM potentiometer for 10.00 Vdc on
the voltmeter. (See Fig. 4-9.)
5 Reattach the meter that is normally connected to terminals 7(-) &
8 (+). Observe polarity.

Calibrating the 4-20 mA Proportional Output
You must calibrate the speed switch if the standard proportional output of 4 to 20 mA is changed to :
* 0-5 Vdc using switch Cl, or
* 0-10 Vdc using switch C2
To calibrate the new proportional output
1 Attach a digital voltmeter to terminals 9 (-) & 10 (+).
2 Apply 10% of the full-scale frequency to input terminals 5 (+), 6 (-).
3 Adjust the PROP OUT ZERO adjust potentiometer (See Fig. 4-10,
below) to yield 10% of full-scale proportional output on the
voltmeter.
Fig. 4-10 The PROP OUT ZERO and PROP OUT SPAN adjustments are located in the upper right corner under the top plate of the SST-2000A/H.
PROP
PROP OUT SPAN
A Apply 100% of full-scale frequency to terminals 5 (+) & 6 (-).
5 Turn PROP OUT SPAN adjust potentiometer (See example below)
to yield 100% of full-scale proportional output on the voltmeter .
6 Repeat steps 2, 3, 4, and 5 three or four times to assure accuracy.
EXAMPLE: A unit calibrated for 0-500 Hz input is being recalibrated to 0-10 Vdc proportional output (from 4-20 mAdc proportional output).
•
* Apply 10% of full-scale (50 Hz) to terminals 5 (+) a 6 (-).
» Adjust PROP OUT SPAN adjust potentiometer to yield 1 .000 Vdc on the voltmeter.
* Apply full-scale frequency (500 Hz) to terminals 5 (+) &
* Turn PROP OUT ZERO adjust potentiometer to yield 10.00
Vdc.
* Repeat 3 or 4 times for accuracy.
Calibrating the Speed Switch
Programming Set Points and Relays
Remove the top plate from the SST-2000A/H to reveal DIP switches B and C.
Use DIP switches B and C to program relay set points to:
* energize (OFF) / de-energize (ON) on alarm
* non-latch (OFF) / latch (ON) on alarm
+ actuate SPST (OFF) / DPDT (ON) trip on alarm
* change proportional voltage output
Fig. 4-11 The DIP switch settings available to you depend on the model of speed switch you purchased:
4 SST-2400A/H series switches have four set point relay adjustments (DIP switches B and C).
* SST-2200A/H series switches only
have relays 1 and 2 (adjustable
using DIP switch C).
* SST-2000A/H switches have no set
point relays.

SENSITIVITY
Higher sensitivities can be more vulnerable to noise.
To raise sensitivity Turn the SIGNAL SENSITIVITY potentiometer (Fig. 4-12) clockwise. At full clockwise rotation, sensitivity is approximately 5 mVrms.
To lower sensitivity Turn the SIGNAL SENSITIVITY potentiometer counterclockwise. At full counterclockwise rotation, the sensitivity is approximately 100
mVrms.
Desensitizing Contact Closure
Jumper terminals 30 and 11 to desensitize the unit to about 1 Vrms. Signal Sensitivity pot setting does not affect this procedure.
