Status indicator LEDs
- Standby
- Purge
- Ignition
- Pilot
- Main
- Modulate
- Flame On
- Alarm
The LEDs will shortly blink as soon as power is applied to the
DBC2000 and then as soon as there is a heat demand,
indicate the burner sequence.
The LEDs are also used to indicate faults. For example, if a
loss of flame signal occurs during RUN, the LEDs for Alarm,
Flame and Main will blink the fault code.
Jack plug
The flame signal can be measured using the jack plug (Ø
3.5mm) on the front, using a microampere meter. The
measuring device must be capable of reading microamperes
between 2 and 15~20 µA.
CAUTION
Although the voltage on the jack plug is of low
voltage, it is not considered to be safe when touching
the wires connected to the jack plug, in case of a
malfunction of the device. Therefore avoid touching
the lead wires to avoid an electrical shock.
Reset switch
When the DBC2000 is in Lockout condition* press
the internal or remote reset button one time to reset
the DBC2000 and stop the alarm. The reset button
must be held for a minimum of 3 seconds.
If the heat demand is still present, the DBC2000 will
perform the start sequence normally when the fault
condition has been resolved. Otherwise the lockout
will repeat.
If during the lockout condition the DBC2000 is de-
energized and power is reapplied afterwards, the
DBC2000 will remain in lock out (non-volatile lock
out).
A remote reset push button switch can be connected
between terminals 15 and 19 (Standard Model) or
between terminals 15 and 18 (Enhanced and
Ultimate Models). The functionality of the remote
reset is the same as the red push button on the front
of the device, with one exception; the remote reset
may occur only 5 times during 15 minutes of
operation, whilst the internal reset button is
unlimited.
* Remark:
Lockout condition refers to the state the DBC2000 is
in after a safety shut-down occurs and the lockout
timing (20 Seconds), plus the post purge timing (15
Seconds - if enabled) have been completed. For
safety reasons the reset button is disabled
immediately after a safety shut-down until both of
these above timings are completed.
The lockout timing is fixed at 20 seconds for all
models, to allow time for the air dampers to return to
the start position, and to allow a safety time between
ignition attempts, for applications without pre- and
post-purge.
Note: The Alarm and LED's will indicate the fault
immediately, but cannot be reset until the unit has
progressed to the Lockout Condition.
