What is the reason of bridging the 19-20 edges on connector E at Sepam 80 series

 Question
What is the reason of bridging the 19-20 edges on connector E at Sepam 80 series?
Otherwise we have Code 1 Error.

Answer
Connector E is a 20-pin connector on Sepam 80 base dedicated for:
- 3 phase voltage V1, V2, V3 inputs
- 1 residual voltage V0 input.
- 2 residual current I0, I'0 inputs.

The terminals 19-20 of Sepam 80 series Voltage connector E are part of Self Test Diagnose of Sepam 80 Voltage connectors.
That is the reason to bridge them.
When these terminals are bridged, an internal diagnosis signal "DPC = detection of plugged connectors= true" is created.
In absence of DPC bridge between terminals 19-20 of Connector E, the Self test Diagnosis of relay it give Fault Message on display as follows:
- if it has MCS025(Synchrocheck module) present the Fault Message is 5 - MCS0265 Not available - Internal Fault error.
- if it has not MCS025 present, the Fault Error is 1 - The hardware configuration is incorrect or incomplete and Connector in position E is display in red on SFT 2841 Hardware configuration screen.

These information are explained into Sepam 80 series Installation Manual SEPED303003EN,  at pages:16, 135, 161 and 163, attached in copy.
