H. INITIAL SET-UP
The PBG
is factory adjusted to conform to capacity and ignition limits.
Although the burner
should require no adjustment upon initial set-up, several adjustments can be made in situations
where the burner needs to be tuned to the application.
1. Combustion Air
If using a combustion air valve and actuator, the valve travels 90
from closed to the
fully open position. The valve is designed for use with a directly coupled IC40
actuator, which is controlled by a 4-20 mA input signal. The air valve must be at the
ignition position to light the burner, which for most applications will be about 20°
open. For applications that require special control motor settings, the IC40 can be
reprogrammed in a variety of different ways using Opticord adapter, (P/N 74960437)
a laptop computer, and a free software package.
A third-party actuator may be used, and Hauck supplies a universal connection kit.
Operationally, the actuator must control the valve in the same manner, and be able
to provide the same ignition point.
If the air is controlled by VFD, the motor will operation between 60Hz at high fire and
15Hz at low fire. In certain applications, such as those operating under pressure, it
may be necessary to increase the low fire frequency to satisfy the air pressure
switch. Applications that have a 50 Hz supply voltage, should select the VFD option
for the ability to fire at the rated high-fire capacity. Applications with a 50 Hz supply
voltage that do not use a VFD will have a de-rated burner capacity and require
different burner settings.
A manual air valve handle may be used to control the air flow to the burner. In a
fuel-only control application, the manual handle has the ability to be fixed, and may
be the desired method of air control.
WARNING
Adjustment of this equipment by unqualified personnel can
result in fire, explosion, severe personal injury, or even death.
NOTE
The use of a third-party actuator without a BCS may require additional
electronic components to be installed and wired by the customer.
