About your speed switch
The SST-2000A/H series is a speed switch and signal transmitter that provides
alarm set points for over- and underspeed control for sequential, startup, and
shutdown switching for:
tengines
tmachines
tI/P drivers
tinstrumentation
tprocess control
trecording
tmeasurement
How it works
The SST-2000A/H accepts a full-scale frequency input value from 0–0.1 Hz
(6 pulses per minute) to 0–50,000 Hz. Standard: 0–80 Hz to 0–20,000 Hz.
Examples of input devices include:
tpassive or active magnetic pickups
tshaft encoders
tcontact closures
tflow meters
tphotocells
The speed switch converts frequency input (speed, rate) into linear proportional
dc outputs:
t0–1 mA (standard - meter out)
t4–20 mA (standard - proportional out)
t0–5 Vdc (switch selectable)
t0–10 Vdc (switch selectable)
It provides 0, 2, or 4 relay trip set points (depending on the model)

Chapter 1
When the SST-2000A/H Series Speed Switch/Transmitter is
used as the primary overspeed shutdown device, it must be
tested regularly.

Installing the SST-2000A/H

Mounting the unit
The SST-2000A/H is installed using standard hand tools. It is generally mounted
in a panel or enclosure using standard practices.
About Electrical Connections
Internal Commons, Isolation
Signal input (low side, terminal 6) is common to the auxiliary output (low side,
terminal 7), to the dc supply (terminal 4), and to the main proportional output
low side (terminal 9). Relay contacts are always isolated
When powered with ac: all circuitry is isolated from the power line by the built-in
supply transformer
When powered with dc: the transmitter output is not isolated from the dc power
source. Any load driven by the transmitter (i.e. recorder, controller, etc.) must
have the same common as the negative side of the dc supply. Install a current
loop isolator between the 4–20mA output and the load if the load does not
reference the same common as the SST-2000.
10
Chapter 2
Install a current loop isolator between the 4–20mA output
and the load if the load does not reference the same
common as the SST-2000A/H.
WARNING: AVOID DAMAGE WHEN DC-POWERED
Fig. 2-1Electrical
Connection Drawing.
Use shielded cable:
connect ungrounded
shield to terminal 4.
Route power line and
relay connections
separate from signal
meter and reset lines
to prevent electrical
noise interference.
Terminals 4, 6, 7, and
9 are internally tied
together to circuit
common unless unit
has signal isolation
transformer. In that
case, terminal 6 is
isolated.

Connecting Signal Inputs
Connecting a PG-278 Pulser
Connect signal source Common to terminal 6 on the SST-2000A/H. Connect
signal HI to terminals on the SST-2000A/H.
Terminals 11 and 30 on the SST-2000A/H are jumpered to create a one volt
threshold.

Chapter 3
Powering External Devices

Powering an SPD-100, SPD-700, or other frequency
instruments
The SST-2000A/H has a repeater output that can be used to power external
frequency instruments.
A square wave (14-volt peak-to-peak, zero-based, positive-going) is brought out
at terminals 29 and 4 (common) to drive self-powered digital tachometers such as
the SPD-100, SPD-700, and MTH-103D, or to use as a conditioned high level
signal source into counters or other instruments. The frequency of the signal is
equal to that being applied at the signal input: terminals 5 (+) & 6 (–).
This output has an internal resistance of 1 kΩ.
Using DPM-105 meters as external speed indicators
You can use the DPM-105 as an external indicator. You can connect one or
more DPM-105 meters to your SST-2000A/H.
The 0-1 mA meter output of the SST-2000A/H [terminals 7 (–) and 8 (+)] is
factory-calibrated into an external load of 40 Ω. The load resistance of the
DPM-105 is 95 Ω.
Connecting one DPM-105
1On the DPM-105, retain the jumper across terminals 1 and 2.
2Connect the meter as shown in Fig. 3-3.

tKeep the jumper

tConfirm the meter is properly connected to the SST-2000A/H.
tUse a frequency generator (e.g. F-16) to apply full-scale frequency
to terminal 5 (HI) & 6 (COM) on the SST-2000A/H. Maximum
signal input is 50 Vrms for a standard unit.
tAdjust the METER CALIBRATE potentiometer on the
SST-2000A/H for the appropriate full-scale reading on each
DPM-105.
tUse a DPM-105 data sheet, if necessary, to calibrate the
DPM-105 meters.
Connecting more than one DPM-105
1Remove the jumper across terminals 1 and 2 on each DPM-105.
2Connect the meters as shown in Fig. 3-4.
3Calibrate the SST-2000A/H.
tConfirm the meter is properly connected to the SST-2000A/H.

unit.

Powering Zero Velocity Pickups and Other Loads
The regulated 14 Vdc supply brought out at terminals 11 (+) & 4 (–) has a
capacity of 40 mA. This output can power zero velocity pickups (e.g. M928) and
digital indicators like a DPM-105.
1Connect the M928 pickup as indicated inFig. 3-5.
2Jumper terminals 11 and 30 to desensitize the input signal to a 1.0 V
threshold.
3Adjust signal sensitivity if necessary. See page 27 for instructions on
how to adjust input sensitivity.

Driving an SPV-200 Solenoid Pneumatic Valve
The SPV -200 coil has a resistance of 50 Ωand requires 6 Vdc to trip.
Switching the Regulated 14 Vdc Supply
The regulated 14 Vdc supply at terminals 11 (+) & 4 (–) does not have the
capacity to drive the SPV-200 continually.
When the SST-2000A/H speed transmitter is supplied with the Pneumatic Trip
Option for Overspeed, Relay 1 transfers for only 100 milliseconds on overspeed;
the 14 volt supply can then be used with a series limiting resistor to power the
pneumatic trip.
Use a ¼ watt, 47–50 Ωresistor in series with the 14 volt supply.
Switching 28 Vdc
When switching 28 Vdc into the coil, use a 5–10 watt, 180 Ωresistor in series
with the SPV-200 coil.
