Setting The Probes And Set-Points; Configuration Of A Temperature Probe At X60 Door - Unigas N880X Manual

ExtLC X5-03 = three-point external controller (X5-03 terminals)
Int LC = internal controller (LMV5x) (it switches between 2 set points, W1,W2 set thought AZL. the switch from W1 and W2 is realized opening/closing
the LMV5x... terminals X62.1, X62.2).
Int LC Bus = internal controller and set point setting via bus connection
Int LC X62 = internal controller (LMV), but set point is externally controlled by means of a voltage/current signal on X62 terminals
Ext LC X62 = external controller, the burner output is controlled by means of a voltage/current signal on X62 terminals
Ext LC Bus = external controller, the burner output is controlled via bus
ATTENTION: in case of FGR, it is not possible to connect a modulating temperature probe at the X60 door of the LMX5...
See the proper chapter for configuration.

6 Setting the probes and set-points

If the LMV5x internal load controlled is used, a temperature or pressure probe can be connected to the terminal X60 or X61. In this case, set the type of
probe and its operating range.
6.1

Configuration of a temperature probe at X60 door

ATTENTION: If the external load controller is set do not connected to terminals X60 or X61.
ATTENTION: If the burner is equipped with FGR with temperature compensation a Pt1000 must be set.
ATTENTION: Depending on the sensor, the value is visualized as °C or bar.

Probe Description
Pt100 Temperature sensor Pt100 at the input X60, internal temperature limiter function = activated
Pt1000 Temperature sensor Pt1000 at the input X60, internal temperature limiter function = activated
Ni1000 Temperature sensor LG-Ni1000 at the input X60, internal temperature function = activated
TempSens Temperature sensor at the input X61, internal temperature switch function = deactivated
PressSens Pressure sensor at the input X61, internal temperature switch function = deactivated
Pt100 Temperature sensor Pt100 at input X60 for temperature controller and temperature limiter function and temperature sensor Pt1000 at input
Pt1000 X60 additionally for temperature limiter function
Pt100 Temperature sensor Pt100 at input X60 for temperature controller and temperature limiter function and temperature sensor LG-Ni at input
Ni1000 X60 additionally for temperature limiter function.
No Sensor No actual value sensor (e.g. in the case of external predefined loads and without internal temperature limiter).
ATTENTION: If a boiler second probe is to be connected to terminals (1000 Ohm only), internal functions TL_ThreshOff and
DiffIntervTL_SD_On are activated automatically (see paragraph SETTING FUNCTIONS "TL_ThreshOff" AND "TL_SD_On").
