11.2.2. Analog Output current values in dependence of Fail-Safe Error Codes

The relay is controlled by the temperature selected on the display. If any failsafe code appears
on the display, the relay changes to the "abnormal" state. The exception is the "dirty window"
condition. This causes the relay to change state, leaving a normal numerical temperature
output.

If two or more errors occur simultaneously, the error with the highest priority overrules the lower
priority errors. The highest priority error will be displayed on the 7-segment temperature display
and the assigned analog output (current) value (see Table 12) will be set. For instance, in 2-
Color mode, if the internal ambient temperature is over the limit and the attenuation is to high
too, the unit outputs EIHH to the temperature display and sets an analog output current of 21
mA on the analog current loop output lines. However, since 2-Color wide band and narrow band
temperatures may all be presented simultaneously through RS485 or LAN / Ethernet interface,
their over and under range conditions are independent.
