Introduction

MCB115 Programmable I

• As a general extension of the I/O selection available on the Control Card, e.g. for multi zone control with
three pressure transmitters.

• Turning the drive into a decentralized I/O block supporting Building Automation System with inputs and
outputs.

• Support the Extended PI controllers with I/Os for setpoint inputs, transmitter/sensor inputs and outputs
for actuators.

• Digital output used for either driving a relay, input to commonly used PLC I/O card or as input to another
drive in a sequential controlled application.

/O Option Card is supposed to be used e.g. in the following cases:

In/Outputs

This option has programmable inputs/outputs which extends the number of inputs and outputs available for
the drive.
This option has three analog inputs which can work as voltage 0-10V or 2-10V, current 0-20 mA or 4-20 mA,
temperature input for PT1000 or NI1000 sensors.
This option has three outputs which can work as voltage 0-10V or 2-10V, current 0-20 mA or 4-20 mA or digital
output.

The analog inputs can be used for reference or process feedback for all the PID controllers.

Terminals

There are 3 inputs and 3 outputs on the option. Inputs are named X49/1, X49/3 and X49/5.
Outputs are named X49/7, X49/9 and X49/11.

• Resolution for the analog voltage input is 10 bits.

• Accuracy for the analog voltage input is better than +/- 1%.

• The analog voltage input is continuously able to withstand +/- 28V DC.

•

Impedance for the analog voltage input is equal to 10 kΩ.

• Sampling rate at inputs is 2 Hz as minimum.

• Resolution for the analog current input is 10 bits.

• Accuracy for the analog current input is better than +/- 1%.

• The analog current input is continuously able to withstand +/- 29mA DC.

•

Impedance for the analog current input is 200 Ω

•

PT1000 temperature sensor (1000 ohm at 0°C). Characteristic according to IEC60751.

•

NI1000 temperature sensor (1000 ohm at 0°C). Characteristic according to DIN43760.

•

Accuracy in temperature at -50°C is better than 1 Kelvin. Accuracy in temperature at +150°C is better

than 2 Kelvin.

• Max cables length for temperature sensors, is 50 metres non-screened / non-twisted wires. Cable im­pedance should be kept low as every 3.85 Ω in cable will give a misreading of 1 Kelvin.

Mounting Guidelines

Mounting of Option Modules in Slot B

The power to the frequency converter must be disconnected.

WARNING

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before serv­icing. Follow proper lock-out/tag-out procedures to ensure the power cannot be inadvertently energized. For frequency
converters or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s
literature for allowable waiting periods for discharge of capacitors. Verify with an appropriate voltmeter that all capacitors
are discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious
injury.

For A2, A3 and B3 enclosures:

• Remove the keypad, the terminal cover, and the keypad frame from the frequency converter.

• Fit the MCB115 option card into slot B.

• Connect the control cables and relieve the cable by the enclosed cable strips.
Remove the knock out in the extended keypad frame delivered in the option set, so that the option
will fit under the extended keypad frame.

• Fit the extended keypad frame and terminal cover.

• Fit the keypad or blind cover in the extended keypad frame.

• Connect power to the frequency converter.

• Set up the input/output functions in the corresponding parameters.

• Remove the keypad and the keypad cradle

• Fit the MCB115 option card into slot B

• Connect the control cables and relieve the cable by the enclosed cable strips

• Fit the cradle

• Fit the keypad
