WARNING
Fire or Explosion Hazard.
Can cause property damage,
severe injury, or death.
Carefully follow safety requirements when installing a
burner control.
CAUTION
Electrical Shock Hazard or Equipment/
Control Damage.
Can cause electrical shock or equipment
damage.
Disconnect power supply before beginning
installation.
IMPORTANT
1. Wiring connections for the relay modules are unique;
refer to Fig. 3-2 or the appropriate Specifications for
individual subbase wiring.
2. Wiring must comply with all applicable codes,
ordinances and regulations.
3. Wiring must comply with NEC Class 1
(Line Voltage) wiring.
4. Loads connected to the DBC2000E must not exceed
those listed on the relay module label or the
Specifications; see Table 3.
5. Limits and interlocks must be rated to simultaneously
carry and break current to the ignition transformer and
fuel valve(s).
6. All external timers must be listed or
componentrecognized by authorities who have proper
jurisdiction.
7. For on-off gas-fired systems, some authorities who
have jurisdiction prohibit the wiring of any limit or
operating contacts in series between the flame
safeguard control and the main fuel valve(s).
8. Two UV flame detectors can be connected in parallel.
9. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used
in accordance with the instructions, can cause
interference with radio communications. It has been
tested and found to comply with the limits for a Class
B computing device of Part 15 of FCC rules, which
are designed to provide reasonable protection
against such interference when operated in an
industrial or commercial environment. Operation of
this equipment in a residential area can cause
interference, in which case, the users, at their own
expense, may be required to take whatever measures
are required to correct this interference.
10. This digital apparatus complies with the requirements
as stated in the EN298:2003.
11. Do not install the Burner Controller under any
circumstances in the following locations.
① Where chemicals or corrosive gases are present,
such as ammonia, sulfur, chlorine, ethylene
compounds, acids, etc.
② Install the relay module where the relative
humidity never reaches the saturation point. The
relay module is designed to operate in a
maximum 85% relative humidity continuous,
noncondensing, moisture environment.
Condensing moisture can cause a safety
shutdown or damage the device.
③ Where temperatures exceed the maximum
specification for this device.
④ Where vibration exceeds 0,5G continuous
vibration.
12. Do not bundle power wiring and high voltage ignition
cable with the flame detector wiring, or run them in
parallel within the same conduit. High voltage cables
must be kept separated at least 10 cm from the
Burner Controller.
13. Use proper grounding work in accordance with the
engineering standards for electrical equipment
14. Connect the high voltage cable of the ignition
transformer properly to the ignition electrode. A poor
connection can cause an electrical shock or damage
the equipment. Additionally the ignition transformer
must be properly grounded according the standards.
