Key to Layout (Fig. 18) - (Fig. 19)
BT
- Temperature probe
BP
- Pressure probe
IN
- Manual burner stop switch
MB - Terminal strip
RS
- Remote lock-out reset button (if present)
S
- Remote lock-out signal
TL
- Limit control device system: this shuts down the burner
when the boiler temperature or pressure exceeds the set-
point value.
TR
- High-low mode control device system: this controls oper-
ating stages 1 and 2 and
The TR load control is not required when the regulator
RWF40 is connected as its function is performed by the
regulator RWF40 itself.
TS
- Safety control device system: this operates when TL is
faulty.
The burner is factory set for two-stage operation
and the TR remote control device that commands
light oil valve V2 must therefore be connected.
WARNING
Alternatively, if single stage operation is required, instead of con-
trol device TR install a jumper lead between terminal 5 and 6 of
the terminal strip.
Calibration of thermal cut-out 17) (Fig. 1 page 7)
This is required to avoid motor burn-out in the event of a signifi-
cant increase in power absorption caused by a missing phase.
If the motor is star-powered, 400 V, the cursor should be
positioned to "MIN".
If the motor is delta-powered, 230 V, the cursor should be
positioned to "MAX".
Even if the scale of the thermal cut-out does not include rated mo-
tor absorption at 400 V, protection is still ensured in any case.

NOTE:
Burners RL 70/M - RL 100/M - RL 130/M leave the factory pre-
set for 400 V power supply. If 230 V power supply is used,
change the motor connection from star to delta and change
the setting of the thermal cut-out as well.
The RL 70/M - RL 100/M - RL 130/M burners have been type-
approved for intermittent operation. This means they should
compulsorily be stopped at least once every 24 hours to en-
able the control box to perform checks of its own efficiency
at start-up. Burner halts are normally provided for automati-
cally by the boiler load control system. If this is not the case,
it is necessary to apply in series with IN a timer switch that
turns off the burner at least once every twenty-four hours.
These burners are also fiitted for the continuous operation,
if they are equipped with the control box LANDIS type LOK
16.250 A27 (interchangeable with the burner control box
LANDIS LAL 1.25).
Do not invert the neutral with the phase in the
electrical supply line.
