H30951B Control and power electronics for ATTACK DPX Combi Pellet 25/30/35, PELH30A & PELHB25

H30951B Control/power electronics for Attack pellet burner

The H30951B Control/Power Electronics is the central control and power module for various Attack Pellet Burner and Combined boiler systemsIt takes over the complete control, monitoring and power management of all relevant components in pellet operation.

Compatible attack devices (excerpt)

According to exploded views and spare parts lists, the H30951B is installed in, among others, the following Attack devices:

• ATTACK DPX COMBI PELLET 25, 30, 35
  • z.B. Device family #110 PELH30ACP
  • Construction periods u.a.: 10/2014 – 7/2018 and from 8/2018 (depending on the version)
• ATTACK PELH30A (Pellet burner unit, from 10/2014)
• ATTACK PELHB25 (Pellet burner 25 kW, from 10/2014)

The H30951B is listed there as a separate item in the spare parts plan and is part of the assemblies with the codes z.B.:

• PELH30A, PELHB25
• In combination with other relevant components such as H30970A, H30806B, H30808, H30809, H30820, H30980, ADF25640, PELH30830A u.v.m.

This makes the H30951B particularly suitable for Attack pellet burners in the power range of 25 to 35 kW relevant, which are found in various boiler series such as DPX Combi Pellet be used.

Function and tasks of the H30951B

The H30951B is a combined Control and power electronicsIt handles both the intelligent control (microcontroller control) and the control of the consumers (power section):

1. Burner control (Control Electronics)
   • Evaluation of sensors (z.BTemperature sensor, exhaust gas temperature, flame sensor, possibly vacuum sensor)
   • Control of the process flow of:
     • Starting and ignition process
     • Transition to continuous operation
     • Power modulation
     • controlled shutdown process
   • Implementation of the heating programs and safety strategies stored in the device

2. Power control (Power Electronics)

   • Control of:
     • Pellet auger(s)
     • Ignition device/ignition cartridge
     • Blower/combustion fan
     • cleaning and discharge mechanisms (if applicable)
   • Switching of consumers via relays or...electronic circuit breakers
   • Power supply for the control electronics and the connected sensors/actuators

3. Security and incident management

   • Monitoring of overtemperature, flame loss, underpressure or exhaust gas faults
   • Introduction of safe shutdown in case of malfunction
   • Edition of Error codes/fault messages to the control unit of the Attack boiler

4. Communication with control unit and boiler control

   • Interface to the operating and display unit (display, buttons)
   • Transfer of status, temperature and fault information
   • Interaction with the higher-level boiler or heating control system (release, power request)

Typical errors that indicate a control system malfunction

The H30951B Control/Power Electronics is considered complete replacement module used when:

• the Pellet burner no longer starts or goes out uncontrollably
• Individual outputs (ignition, auger, fan) can no longer be controlled, even though the components themselves are fine.
• Recurring or unexplained error messages problems occur that cannot be attributed to sensors, wiring, or peripherals
• Visible damage to the electronics is present (burnt components, defective relays, swollen capacitors)

By replacing the H30951B, the full range of functions of the pellet burner It can be restored, provided all other components are intact.

Advantages of the original H30951B for Attack pellet burners

• Original spare part matching the corresponding Attack series
• tailored to:
  • ATTACK DPX COMBI PELLET 25, 30, 35
  • ATTACK PELH30A
  • ATTACK PELHB25
• ensures correct combustion, high efficiency and stable performance in pellet operation
• secures the Compliance with safety functions according to manufacturer's specifications
• optimal compatibility with other Attack components (z.B. PELH30851, PELH30800A, PELH30807B, PELH30830A, sensors TS215, TH31, TH23A etc.)

Important information regarding ordering and exchanges

• Please note before ordering:
  • Boiler/burner nameplate check (z.BATTACK DPX COMBI PELLET 25/30/35, Year of manufacture/Serial number)
  • existing electronic circuit board to the marking H30951B control
• For safety reasons, replacement should be carried out by a Specialist company/heating specialist take place:
  • Mains voltage 230 V
  • Correct connection assignment and parameterization required
  • If necessary, adaptation to existing sensors and peripherals

Scope of delivery

• 1x original Attack control board H30951B
