• Time delay on the alarm
The relay time delay is adjustable from 000.0 to 025.0s., in 0.1s increases.
It is active both on switching and switching back.
• Positionning of the time delay
Time delay on the switching on alarm.
Time delay on the switching on alarm and out of alarm.
• Alarm recording
Allows recording the alarm after a setpoint has been passed. When the
measure reverts below the alarm setpoint, the relay remains on and the
led blinks to warn the user that the setpoint has been passed (to reset
the alarm recordings to 0 see the menu p19 ).
Note: An exit from the mode programming with saving of the configura-
tion will reset the alarm recordings to 0.
• Display of alarm messages
A programmed alarm message can be made to appear alternating with
the measure. The message will appear only during the alarm, that is to
say while the associated led is lit.
• Setting of the setpoints: There are 2 ways to adjust setpoints:
- either in mode programming entering the correct access code
- or by pressing simultaneously and if the access to a quick
entering has been allowed on the programming of the code (see page 18) .
· On the relays:
No influence on the relay in case of self-diagnosis error
Relay de-activated (coil supplied) in case of self-diagnosis
error
Relay activated (coil supplied) in case of self-diagnosis error
Note: The led is either still or lit according to its programming in the
menu rELAY.
· On the analog output
If a return value has been entered
Value between: 0 and 22 mA (current output)
or 0 and 11 V (voltage output)
•
Sensor rupture
The sensor rupture can be detected on the inputs mV, Tc, Pt100, Ni100,
∆ PT100, resistance, and current if down and full scale > 3.5 mA.
The sensor rupture information can be reported
:
·
On the relay
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.
· On the analog output
If a return value has been entered
Value between: 0 and 22 mA (current output)
or 0 and 11 V (voltage output)
· On the display : Message
Note
:
The sensor rupture detection has a priority over the self-diagnosis .
• Disconnection of the sensor rupture (If mV or temperature input)
The sensor rupture can be disconnected in order not to disturb some
calibrators which may be sensitive to the rupture detection current.
In the menu :
Disconnection of the sensor rupture, or not
Sensor rupture detection on
Disconnection of the sensor rupture
4.6.4 Safeties:
• Self-diagnosis:
The meter permanently watches its components for any drifts. The self-
diagnosis serves to warn the user in case of abnormal increase of these
drifts before they may provoque false measures.
The self-diganosis error information can be reported :
· On the display : An error message appears alternating with the meas-
ure; an error code is registered and can be read in the menu About (see
page 18).
Coding:
1 : Programming error
4 : Offset error
8 : Input calibration error
16 : Output calibration error
32 : Cold junction compensation error
64 : Upper or lower electrical overstepping of the input.
If the instrument detects for instance an offset error (4) and a program-
ming error (1) the error code will be 5 (4+1).
