A complete BurnerLogix Z System includes the ZB110 (ZB230) chassis equipped with the type of
flame amplifier required for the application, appropriate flame detector, plug-in programmer module,
appropriate temperature/pressure transducer, wiring base and alpha-numeric display. Interchangeable
YP1XX type programmer modules allow for complete versatility in selection of function, timing and
flame failure response times. Refer to BurnerLogix PROGRAMMER SELECTION later in this doc-
ument for the various combinations of programmer and display modules.
The ZB110 (ZB230) is a chassis/flame amplifier module complete with mounting screws and blank
display module. The display module (BLV512 or BLL510), if required, must be ordered separately.
Functions such as pre-purge time, recycling or non-recycling interlocks, high fire proving interlock,
and trial for ignition timing of the pilot and main flame are determined by the programmer module.
The BurnerLogix Z System can be used with ultra-violet, autocheck infrared, flame rod, self-check
ultraviolet flame scanners or direct coupled by choosing the proper chassis/flame amplifier module.
Wiring bases for the BurnerLogix Z control are available pre-wired with 4 foot lead wires color
coded and marked for easy installation or with an integral terminal block capable of a accepting up to
2 X 14 AWG wires. The wiring base terminal block is available with knockouts for conduit or open
ended for cabinet mounting. The pigtail wiring base is 4" X 5" and the terminal block wiring base is
4" X 7".
Additional functions of the BurnerLogix Z System include:
•
A non-volatile memory which allows the control to remember its history and present position
even when power is interrupted.
•
A consistent flame signal read-out via display module or 4-20 mA output.
•
Read-out of main fuel operational hours and complete cycles via display module.
•
Modbus communications via RS485 multi-drop link.
•
Proof of fuel valve closure during off cycle.
•
Burn-in time of program parameters occurs after 8 hours of main valve on time.
•
A run/check switch which allows the operator to stop the program sequence in any of four
different positions (Purge, PTFI, MTFI or Auto).
•
Remote Display mounting with NEMA 4X/IP66 protection.
•
Remote Reset
•
Programmable communication baud rate allows for DCS compatibility.
•
Keypad selectable language readout.
•
Revert to pilot can increase burner turn down.
•
Additional terminals provided for applications requiring additional inputs and outputs.
CAUTION: While programmers are mechanically interchangeable in that they mate with a
common chassis/amplifier module, you should select the correct model for your application.
Inappropriate application of a control could result in an unsafe condition hazardous to life
and property. Selection of a control for a particular application should be made by a compe-
tent professional, such as a boiler/burner service technician licensed by a state or other gov-
ernment agency.
WARNING: Electro-mechanical high steam pressure or high water temperature limits must
remain in the running interlock circuit of the flame safeguard control.
