2. Pilot Device (D3, D4) MT1311/ MT2211 only. HOA switch inputs. These dry inputs are wired to a door-
mounted pilot device such as an HOA switch.
•
SG - Common
• D3 - Hand Signal
• D4 - Auto Signal
3. Dry Inputs - (D1, D2) MT1311/ MT2211 only. These connections
provide input for a wide selection of switches or programma -
ble controls, such as use of float switch (High Float/Low Float)
inputs.
•
SG - Common
• D1 - Auto Run/Low Float
• D2 - Shut Down/High Float
4. Voltage (Wet) Inputs - (V1, V2) MT1311/ MT2211 only. These connections provide input for various
types of voltage control signals. This wet input can be used for remote start/stop of a pump motor,
such as in an irrigation system, building management control, or programmable logic control. Refer to
“Fill/Drain using Float Switches” on page 27 for further information.
• Voltage input pairs accept AC/DC voltages 12 V to 240 V± 10%, up to 5 mA.
• Inputs can be programmed to be activated by either an incoming voltage signal (Active High) or a
loss of voltage (Active Low). Default state is Active High.
5. Contactor Control Circuit - (M2, M1) MT1311/ MT2211 only. Provides a factory-wired TRIAC signal
capable of closing up to 2 A contactors at 24 VAC to 600 VAC.
6. Contactor Power Output - (C+, C-) MT2211 only. This factory-wired circuit provides 24 V AC PWM
output to close only FCS manufactured contactors 100AF frame size and smaller.
7. Relay Output - (01, 02) The O1/O2 connectors are the connections for a programmable relay output.
This relay can be configured to close in various situations. Connect an external light, horn, or other
signaling device to the relay output to indicate the fault condition. By default, O1/O2 closes when the
SubMonitor Connect is in the fault condition. These relay contacts are rated for up to 1 A at 240 VAC/
VDC.
8. PT100/PT1000 - (I+, V+, I-/V-) Analog input reading of motor winding and lower bearing temperature
from external sensors.
•
I+ Positive connection for excitation current circuit for two, three, and four wire PT100/PT1000 RTD
sensors.
• V+ Positive connection for voltage sensing circuit for two, three, and four wire PT100/PT1000 RTD
sensors.
• I-/V- Negative connection for both the excitation circuit and voltage sensing circuit for two, three,
and four wire PT100/PT1000 RTD sensors.
9. Insulation Check - (Ground, W) This output puts a small voltage across a motor winding (W) and
ground. A fault occurs if the measured resistance on the motor winding is less than insulation check
resistance trip threshold setting. The default setting is off; the Fault trigger default setting is 500 kΩ;
the Alarm trigger default setting is 1000 kΩ. Refer to
“Insulation Check” on page 33 for further
information.
10. RS-485 Modbus - (-, +, SG) This RS-485 connection is for Modbus RTU communications I/O using
shielded twisted pair cable.These connections provide access for external computer-based monitoring
and control.
•
+ Positive RS-485 wire
• - Negative RS-485 wire
• SG Used for the shield wire
• Termination Switches (above this connector) Leave both 1 and 2 in the OFF position.
