Alarm Output; Factory Default Values; Lock Mode; Mode Setting For The Digital Input Ftc 3 - RayTek XR Operating Instructions Manual

H=500 the maximum current/voltage value is set to 500°C
L=0 the minimum current/voltage value is set to 0°C
Note: You cannot set these values for thermocouple output. The minimum span between the maximum
/ minimum settings is 20 K.

7.5.3 Alarm output

The opto-coupled alarm output can be function and trigger from various temperature variables:
- Internal sensing head temperature (normally open N.O. or normally closed N.C.)
Target temperature, to be set to N.C. (relay contacts are closed while home position) or N.O. (relay
-
contacts are open while home position)
K=0
alarm output open
K=4 Sensor head ambient temperature trigger, relay N.O.
K= 2, XS=125.3 Target temperature trigger, relay N.O., threshold setting to 125.3°C (if U=C is set)

7.5.4 Factory default values

It is possible to reset the unit to the default values.
XF factory default values will be set

7.5.5 Lock mode

The access to the unit is possible via serial interface (software) and via the direct user input (mode
buttons, LCD display). It is possible to lock the buttons. This allows the unit to be accessed only via
software.
J=L direct user input via mode buttons denied

7.5.6 Mode Setting for the digital input FTC 3

The digital input FTC3 can used as follows:
XN=T FTC3 as trigger
XN=H FTC3 with hold function
XN=L FTC3 with laser control function

7.5.7 Ambient Temperature Compensation

In case of compensating the background ambient temperature, the following modes are available:
AC=0 no compensation
AC=1 compensation with a constant temperature value set with command A.
