The information sequence presented on the display is shown in figure 10.
The normal operation and configuration modes present a "timer" which makes the
display return to the process variable, when it shows any other information and no key is
pressed for 1 minute. It does not apply to the Calibration level (Calib. mnemonic). See
item 3.2 on Configuration.
In operating mode, the relay configured to trip alarms with Fail manual reset (See
section 3.2 - Configuration: Levels 5 and 6 – ALAR.3 and ALAR.4) are reactivated by the
following procedure:
(i) The message B.OUT (for RTD or TC input) or BREAK (for 4-20 mA current or 1-5 V
voltage inputs) flashes on the display, indicating that the sensor is broken and the trip alarm
is disabled;
(ii) Redo the connection of the terminal block;
(iii) The display starts to alternately display the words of the process variable and the
mnemonic FAIL (relays 3 and/or 4 disabled);
(iv) Activate relays with trip alarm as follows:
1. Go to CONF and press UP to display the PASSWORD display;
2. Press UP, DOWN and ENTER;
3. FAIL disappears from the display and the display returns to show the
process variable with the trip alarms already reactivated.
