Introduction
This document contains information on the operation, installation and
maintenance of the SC901 Series Signal conditioner for Hazardous Areas.
The SC901 Series signal conditioner accepts input from an accelerometer,
amplifies and filters the signal, then outputs the data in an analog, 4-20 mA
format.

Description
The conditioner is housed in a plastic enclosure suitable for 35mm-din
rail/surface mounting (Figure 2). On the front of the conditioner are electrical
connectors (WAGO 237 series positive force terminal blocks) for the ± 24 VDC
input and ± analog output, in addition to a transducer output BNC connector,
and electrical connectors (WAGO 237 series positive force terminal blocks) for
the ± signal output and ± sensor input. There is also a green indicator light
(Sensor OK) which illuminates when the transducer is properly connected to the
conditioner and working correctly. A user adjustable ZERO adjustment is
located on the front panel for calibration, if required.
The conditioner contains an input conditioning circuit, a gain circuit to
normalize the input to 2 V full scale, a high-pass and low-pass filter, a true RMS-
to-DC converter, and a 4-20 mA generator. A buffered output connection allows
the user to connect across the vibration sensor for on line vibration analysis
and testing of the sensor.

Mounting Instructions
The conditioner case is designed for quick mounting to a 35mm din rail. The
case can be surface mounted via optional mounting feet.

Electrical Connections
1. Connect the 24 VDC input power to the two connectors (24 VDC INPUT±)
on the top front of the signal conditioner.
2. Connect the cables from the transducer to the SENSOR INPUT ±
connectors at the bottom front of the signal conditioner. If power and
transducer are connected correctly, the green XDCR OK light will go on.
3. Connect the desired vibration monitoring test equipment to either the
*SIGNAL OUTPUT ± connector, *BNC SIGNAL OUT connector, or *ANALOG
OUTPUT ± connector.

SIGNAL OUTPUT ± is an unfiltered connection showing the raw signal from the
transducer.
BNC SIGNAL OUT serves the same function as the SIGNAL OUTPUT ±
connection.
ANALOG OUTPUT ± is the filtered connection with a 4-20 mA signal
proportional to full scale output.

Operating Procedure
To operate the Signal conditioner, make sure that all wires are properly
connected, then apply power.
CAUTION: Make sure that power input does not exceed specified limits or
damage to the system may result.
Make sure the green Sensor OK light is illuminated.
If using BNC Signal Output interface with a portable data collector that supplies
constant current power, turn the power supply off in the data collector prior to
collecting data.
Analog Output Zero Adjustment
This section contains test setup and procedures for adjusting the zero. The
zero adjustment has been factory set and normally requires no adjustments. If
an adjustment becomes necessary, it can be accomplished as described below.
For a current output during setup, monitor the output with a DC current meter
connected to the output. A minimum series load resistor of 50 ohms should be
used (maximum load resistor is 1 K). For the voltage output, monitor the output
with a DC voltmeter.
1. Remove transducer input.
2. Adjust the ZERO ADJUST for a 4.00 mA reading.
