Sensor rupture
The sensor rupture can be detected on inputs mV, Tc, Pt100, Ni100,
resistance, and current if the down and full scale > 3.5 mA.
The information of sensor rupture can be reported:
· On the relays
No influence on the relay in case of sensor rupture
Relay de-activated (coil not supplied) in case of sensor
rupture
Relay active (coil supplied) in case of sensor rupture
Note: the led is either still or lit according to its programming in the menu
rELAY.
4.6.3 Safeties:
• Self-diagnosis:
The meter permanently watches any drifts which may occur on its com
-
ponents. The self-diagnosis serves to warn the user in case of abnormal
increase of these drifts before they may provoque false measures.
The information of self-diagnosis error can be reported:
· On the display: An error message appears alternating with the
measure; an error code is registered and can be read in the
menu About
Coding:
1 : Programming error
2 : Offset error
4 : Input calibration error
8 : Output calibration error
64: Upper or lower electrical overstepping of the input
If the instrument detects for instance an offset error (2) and a program
-
ming error (1) the value of the error code will be 3 (2+1).
· On the relays:
No influence on the relay in case of self-diagnosis error
Relay de-activated (coil not supplied) in case of self-
diagnosis error
Relay active (coil supplied) in case of self-diagnosis error
Note : The led is either still or lit according to its programming in the menu
rELAY.
