MET1482 Module

Temperature Sensor Inputs

Sepam™ T81, T82, T87, M81, M87, M88, G82, G87,

G88, and C86 units provide a temperature monitoring

function that checks the connection of each RTD that is

configured.

An RTD FAULT alarm is generated whenever one of the

RTDs is detected as being short-circuted or

disconnected (absent).

To identify faulty RTD(s):

1 Display the temperature values measured by

Sepam™ using the SFT2841 software.

2 Check the consistency of the temperatures

measured:

b the temperature displayed is "****" if the RTD is

short-circuited (T < –35 °C or T < –31° F)

b the temperature displayed is "-****" if the RTD

is disconnected (T > 205 °C or T > 401° F)

MSA141 Module Analog

Output

1 Identify the measurement associated by parameter

setting to the analog output using the SFT2841

software.

2 Simulate, if necessary, the measurement linked to

the analog output by injection.

3 Check the consistency between the value

measured by Sepam™ and the indication given by

the device connected to the analog output.

MCS025 Module Voltage Inputs

Block Diagram

DE51264

Procedure

1 Connect the single-phase voltage generator to the corresponding test terminal

box, using the plugs provided, according to the block diagram below.

2 Turn the generator on.

3 Apply a voltage V

set to the rated secondary voltage V

s sync1

s sync1= V

s sync1 / 3) in parallel between the input terminals of the two

voltages to be synchronized.

4 Use the SFT2841 software to check that:

b the measured voltage difference dV

, frequency difference dF and phase

difference d

φ values are equal to 0

b the close enable sent by the MCS025 module is received on the Sepam™

series 80 logic input assigned to this function (logic input in 1 status in the

"Input, output and LED status" screen)

5 Use the SFT2841 software to check that for the other Sepam™ Series 80 units

concerned by the "Sync-check" function the close enable sent by the MCS025

module is received on the logic input assigned to this function (logic input in 1

status in the "Input, output and LED status" screen).

6 Turn the generator off.
