SATRONIC - Control boxes for oil burners

LEAKAGE TEST WITH BYPASS VALVES
PLEASE NOTE
Check the wiring before starting the system. Faulty wiring
may result in damages to the monitor system and endanger
the safety of the system.
The instrument may be plugged in or unplugged only when
the main switch is set on OFF. The trigger point of the
pressure switch in the bypass system, or the vacuum switch
in the vacuum system, must be set for half of the mains
pressure, respectively the vacuum level.
FUNCTION CHECK
Perform the following checks when starting or auditing the
system:
Bypass system
Testing operation with bypass valve 1 (BV 1), disconnected
from terminal 5:
After the testing period V2, the instrument switches to
lockout (end of yellow area). Testing operation with bypass
valves (BV 1, Term. 6, BV 2, Term. 5) connected transposed:
After the testing period V1, instrument switches to lockout
(end of yellow area).

SAFETY AND SWITCH FUNCTIONS
If the pressure or the vacuum switch contact is stuck, a
lockout will be the result in any case. In both systems,
leakage of the auxiliary valves is also checked. A burner
start-up without a preceding leakage test concluded
positively is impossible. The blower motor of the burner is
switched from the MDP. If for any reason the leakage
programme does not start-up in a normal shut-down, the
blower motor does not turn off. For the next normal switchon,
there is no burner start-up since the air proving switch
contact remains in its operating position.

Testing programme does not operate, programme remains
in the white area:
-> No phase on terminal 9, automatic burner assembly on
lockout.
Programme sequence stops in the black area:
-> Connection terminal 17 to terminal 18 (bypass) or terminal
18 to terminal 19 (vacuum) is missing.
Blower motor does not start:
-> No feedback from the automatic burner assembly on
terminal 4.
Blower motor does not turn off:
-> Permanent phase on terminal 4, programme switching
system defective.
