(4) TC Short (only for YTA710)

This function detects any short circuit at TC

sensors. When the current is applied and the

resistance of a sensor is (S1 RP23, S2 RP43

in Sensor Diagnostics Information) below the

threshold, the function outputs the Short alarm.

Parameter setting: Set the thresholds at “S1 TC

Short Thrshld” and “S2 TC Short Thrshld” (for

the 2-input specification).

Alarm output: When the resistance is below

the threshold, the function outputs the alarm

of Sensor1 short (AL.12) or Sensor2 short

(AL.13).

• Procedure to call up the display

Device setup → Diag/Service → Diagnostics →

Sensor Diag → Sensor Diag Setting → S1(2)

TC Short Thrshld

Set thresholds.

NOTE

Release the Device Status mask in order to

output the Sensor1 (2) Short alarm. (Initial value

is set in the mask)

(5) RTD Short (only for 3-wire and 4-wire, only

for YTA710)

This function detects any short circuit at the sensor

during the RTD or Ohm measurement. When the

resistance of the Sensor (S1 RC1 to S1 RC4, S2

RC3, S2 RC4 in Sensor Diagnostics Information)

is below the threshold, the function outputs a short

circuit alarm.

Parameter setting: Not necessary

Alarm output: When the resistance is below the

threshold, the function outputs the alarm of

Sensor1 short or Sensor2 short.

NOTE

• Release the Device Status mask in order to

output the Sensor1 (2) Short alarm. (Initial

value is set in the mask)

• In case of 3 wire RTD or ohm connection,

if actual connection and connection setting

is imbalance, unforeseen alarm may be

generated.

(6) RTD Corrosion (only for 3-wire and 4-wire,

only for YTA710)

This function detects any corrosion at the terminals

and along the measurement cables. When the

resistance of the terminals and cables (S1 RC1 TO

S1 RC4, S2 RC3, S2 RC4 in sensor diagnostics

information.) is above the threshold, the function

outputs a corrosion alarm (AL.14 and AL.15).

Parameter setting:

Device Setup → Diag/Service → Diagnostics

→ Sensor Diag → Sensor1(2) Diag setting →

S1(S2) RTD Corr Thrshld,

NOTE

Release the Device Status mask in order to

output the Sensor1 (2) Corrosion alarm. (Initial

value is set in the mask)

(7) Sensor Drift

When the difference between Sensor1 and Sensor2

temperatures becomes larger than the threshold,

this function outputs an alarm. This indicates

that there is some problem at either Sensor1

or Sensor2. The function can be enabled when

Sensor type is set to TC and RTD.

Parameter setting: Set a threshold for the

temperature difference between Sensor1

and Sensor2 at Sns Drift thrshld. When the

threshold is 0.0, the function is not enabled.

Alarm output: When the temperature difference is

larger than the threshold, the function outputs

the alarm of Sensor Drift.

• Procedure to call up the display

Device setup → Diag/Service → Diagnostics →

Sensor Diag →Sensor Diag Setting → Sns Drift

Thrshld

Set thresholds.

NOTE

Release the Device Status mask in order to

output the Sensor Drift alarm. (Initial value is set

in the mask)
