SATRONIC - Control boxes for oil burners

ISO 9001 / EN 29001
Reg. Nr. 10529
Ammeter
For measuring the current from the probe or
photo diode in gas and oil burners with
ionisation, UV or photo-cell flame detection.
INTRODUCTION
The Ionimeter is particularly suitable for measuring the
current from the probe or photo diode in gas and oil burners
with ionisation, UV or photo-cell flame detection.
When measuring this current, the Ionimeter is connected
between the burner control box and the flame detector, by
way of the + and - terminals.
Care must be taken to observe correct polarity when
measuring the current from UV or ionisation detectors.
These measurements are very easily carried out on Satronic
burner control boxes, especially when the appropriate test
baseplate is fitted.
The test baseplate is equipped with two plug sockets for
connecting the leads, and a jumper switch for bridging the
Ionimeter.

CONNECTING THE EARTH TERMINAL
780e/10/92
Additionally, the earth/gound terminal can be connected to
the burner earth (earth terminal on baseplate). By operating
the rocker switch between the minus and earth terminals, in
switch position "earth", an artificial detector probe current
flows directly to the burner earth/ground and activates the
flame relay.
Following this procedure, it is very easy to adjust the
ionisation or UV probe to the optimal setting. Flame signal
strength can be monitored continuously on the Ionimeter,
and burner shutdown, caused by an interruption or a drop
in the current from the detector, is not possible.
CAUTION
In this switch position, the valves remain open after the loss
of the flame.
