LAYOUT (A) - (B)
Burners RL 70/M - RL 100/M - RL 130/M
• Models RL 70-100-130/M leave the factory
preset for 380V power supply.
• If 220V power supply is used, change the
motor connection from star to delta and
change the setting of the thermal cut-out as
well.
Key to Layout (A) - (B)
CMV - Motor contactor
LAL 1.25 - Control box
FR - Photocell
MB - Terminal strip
MV - Fan motor
PO - Oil pressure switch
RT - Thermal cut-out
S1 - Switch for following operations :
MAN = manual
AUT = automatic
OFF
S2 - Button for :
- = power reduction
+ = power increase
SM - Servomotor
TA - Ignition transformer
TB - Burner ground (earth) connection
VM - Delivery pump valve
VS - Delivery pump valve (safety valve)
VS1 - Safety valve on return
VU - Valve on nozzle return
ELECTRICAL CONNECTIONS
set by installer
Use flexible cables according to regulation EN
60 335-1:
• if in PVC boot, use at least HO5 VV-F
• if in rubber boot, use at least H05 RR-F.
All the cables to be connected to the burner ter-
minal strip 8)(B) must be routed through the fair-
leads.
The fairleads can be used in various ways. One
example is given below:
RL 70/M
1- Pg 13,5 Three-phase power supply
2- Pg 11 Single-phase power supply
3- Pg 11 Control device TL
4- Pg 9 Control device
(RWF40)
5- Pg 9 Set up for faird lead
6- Pg 11 Set up for faird lead
7- Pg 13,5 Set up for faird lead
RL 100/M - RL 130/M
1- Pg 13,5 Three-phase power supply
2- Pg 11 Single-phase power supply
3- Pg 11 Control device TL
4- Pg 13,5 Control device
(RWF40)
5- Pg 9 Set up for faird lead
6- Pg 11 Set up for faird lead
