BCS460 for Malt Oven Control
Posted: Sun Feb 22, 2015 3:26 pm
I have purchased a BCS460 for use in a craft malt house drying oven. I have taken my first cut at the programing and I am ready to start laying out the rest of the hardware to make this run. I am hoping the group can provide suggestions for the ancillary devices SSR’s E-stops, Lights etc. The drying oven will have a heat exchanger fed by a boiler heating to 150F (or higher) and an electric duct heater for 150 to 210 F deg F air temp. A variable speed fan will provide air flow for the different stages of the drying process. Reading the posts on the forum and BCS tech info I understand the BCS is only providing a switching signal and does not have enough current to drive ANY loads. I believe the process I am trying to run for the oven is simpler than the brewing end of things I have read about on the forum. Have outlined my DINS and OUTS and am hoping for a string of suggestions and comments to help get this thing off the ground.
1. Process0 E stop Check
2. Process1 Air Flow Check
3. Process2 Oven Overtemp Shutoff
4. Process3 Distiller Malt
5. Process4 Base Malt
6. Process5 Pilsner Malt
7. Process6/7 not used yet.
8. OUT0 Air Recirculation Damper – 120 Vac will control with SSR.
9. OUT1 Boiler – Controlled by Temp1 HW air temp to a 24VDC relay to boiler control. Boiler is either firing or not firing.
10. OUT2 Duct Heater – Controlled by Temp2 air on temp to a 24VDC relay to duct heater.
11. OUT3 Blower Fan off signal. The VFD is a Lenze SMVector drive controller – Control signal 0-5 VDC or 4 - 20 mA input. I believe I can wire the BCS directly to the control inputs on the VFD.
12. OUT4 Blower Fan Speed – High/low speed control - I believe I can wire the BCS directly to the control inputs on the VFD.
13. OUT5 Alarm buzzer/light – Any suggestions for hardware?
14. DIN0 and 1 - E-stop button – Any suggestions for hardware?
15. DIN2 Airflow Sensor – Any suggestions for hardware?
16. DIN3 Alarm reset button – Any suggestions for hardware?
17. TEMP0 to 3 – Intake air, boiler temp, air on temp, air off temp. – Have purchase the BCS compatible temp probes Brewers Hardware.
18. Enclosure is 12” x 18” should be plenty of room.
19. Will have 120vac going into enclosure for 120vac duplex plug and recirculation damper SSR.
20. What other things like wire guides or mounting hardware would be recommended
