PYRO-STAG De-Icer Optimizer Controller Technical presentation 2013
Introduction Meitav-tec is introducing a new concept of De-Icing control Featuring: Works with any existing De-Icing system Energy saving algorithm Simple and quick installation Simple, Logical & accessible user Interface Sequencing between zones allowing larger area coverage with limited power supply Modularity – 1 to 4 contactors
CTU controller – PYRO-STAG
SYSTEM STRUCTURE Outputs To 4 De-Icing Heaters Zone 1 Zone 2 Zone 3 Zone 4 ANY SNOW SENSOR CONTROLLER OUTPUT to HEATERS 24VAC supply
System Features Steady power supply or Sequencing / Staggering between output zones Sequencing / Staggering - 1/2/3/4 or 1+3/2+4 Adjustable Cycle time between zones Off Delay Time - Adjustable in cycles count Adjustable OFF Delay cycles Override operation – activates the system CTU information 24VAC operated DIN RAIL or screws wall mounting Dimensions: 8 x 4 x 2 inches (205 x 96 x 60 mm) Weight: 1 lb. (0.545 kg.) Flammability UL94V-0 IP 20
Electric Layout
Operation Scenario # 1 Zones zones works in staggering with OFF delay De-Icer ON input INDEX: Zone Output ON Zone Output OFF Input from De-Icer End Of Delay TimeStart Delay OFF Time
Operation Scenario # 2 Zones Zone works constantly 3 zones works in staggering OFF delay INDEX: Zone Output ON Zone Output OFF Input from De-Icer End Of Delay TimeStart Delay OFF Time De-Icer ON input
Operation Scenario # 3 Zones Zone works in staggering Every 2 zones are working together OFF delay INDEX: Zone Output ON Zone Output OFF Input from De-Icer End Of Delay TimeStart Delay OFF Time De-Icer ON input
Configurations selection Simple DIP Switch positions define all options Easily modified by technician on site ON S1-1 - # of outputs work in staggering - 2 or 4 S1-2- Outputs linkage - outputs 1 & 3 and 2 &4 are linked or outputs 1, 2, 3, 4 works separately S Sequence step timer - 1, 5, 10, 20, 30, 45, 60, 120 min. S1-6- Delay between outputs On/Off activation S Off Delay # of cycles- 0, 1, 2, 3 delay cycles S2-1- Device Enable/Disable- when disable = all outputs ON
Summary The Meitav-tec De-Icing Sequence device offers solution for installations with large power consumption as it allows to divide power supply to separate zones The PYRO_STAG controller can be used with any existing De- Icing system Simple installation and easy configuration will minimize cost Energy saving algorithm staggering between zones allows large area coverage with lower power consumption Professional Service and JIT availability
