The Motor Monitoring Board (See
) has up to 4 different sections of inputs (depend-
ing on the board part number) as follows:
•
Configurable Analog Inputs
There are 8 configurable Analog Inputs: AI9 -
AI12 (TB2) and AI13 AI16 (TB1). Each input
can be configured to accept one of the following
types of inputs: 3K Thermistor, 10K Ohm Therm-
istor, 50K Ohm Thermistor, Pressure Transducer,
0 to 5 VDC, 0 to 10 VDC or 4 to 20mA. Each
input is configured by a command sent from the
microboard via the serial communications. Each
input is configured by putting either 243 Ohm, 5K
Ohm or 10K Ohm load resistor to ground on the
input. See below for the configurations.
• Digital inputs
There are 2 low voltage DC inputs: DI1 and DI2
(TB7). Each input can be configured in either a
pull-up or pull-down configuration. In the pull-
up configuration, the input is high when the in-
put switch is open; low when closed. In the Pull-
down configuration, the input is low when the
input switch is open; high when closed. Both of
these inputs have an LED (DI1 and DI2) that il-
luminates when the input is high. Each input is
configured by a command from the microboard
via serial communications. There are 2 Optocou-
pler AC/DC inputs: DI3 and DI4 (TB8). These in-
puts can accept either 24 VAC or 24 VDC inputs.
When the input signal is present, the input is con-
sidered active. Both of these inputs have an LED
(DI3 and DI4) that illuminates when the input is
active. There is no configuration on these inputs.
• RTD Analog Inputs
The -001 board can accept up to 8 RTD inputs:
RTD1-RTD4 (TB6) and RTD5-RTD8 (TB5).
There is no configuration on these inputs.
• Vibration Analog Inputs
The -001 board can accept up to 4 Vibration An-
alog Inputs - AI17 through AI20 (TB3). A com-
mand from the microboard, via the serial com-
munications, sets the gain of each input to 1:1,
11:1 or 21:1(default). The gain value transmitted
is programmed by a Service technician using the
VIBRATION GAIN SETPOINT key on the MO-
TOR SETPOINTS Screen. Program Jumper JP1
must always be removed. It is only installed for
manufacturing testing.
