6.13. Recommended sequence of device programming
It is recommended that the initial device programming be carried out in the following sequence:
Configuring
Switching to Manual mode (if the device is not already in it)
Alarm programming
Programming of cold-junction default temperature if there are thermocouple inputs
Setting rate of input display change
Disabling input visualization (skipping inputs on display)
7. CONFIGURATION
Configuring means programming parameters that rarely need to be changed and that are usually defined
once – at installation – such as the parameters defining input use, RTD line resistance, and linear input ranges.
7.1.
Entering configuration mode
At start-up, after the self-test, all LEDs blink for a moment. To enter configuration mode, press
&
while the LEDs are blinking. To exit configuration mode, use the same combination of keys.
Changing the values of the parameters from the configuration parameter group is always possible and is
NOT protected by a password or external access restriction contact.

* the parameter
yc
is present only if the device has at least one thermocouple input.
# denotes analog input number (1...8); it depends on the number of inputs actually present in the device.
After configuration mode is entered,
cF
appears on the upper display, while the lower one shows
the name of the first input -
yc
or
Q1
. To browse the list of input types, use
and
, and to select
an input, press
. The name of the selected input stays on the upper display as long as all its parameters are
being programmed, except for the
PASS
parameter, during whose adjustment the upper display shows
PA
.
The device may be equipped with up to 8 analog and 2 discrete inputs (various numbers may be ordered).
When thermocouple inputs are present, there is also a cold-junction temperature input present.
