CONTROL ACCESSORY TYPE: RZ

FUNCTION

The Control Accessory is used in connection with a Rekumat burner (RB) or Rekumat radiant tube burner (RS) to calculate the switch on time of the built-in twoposition controller in the controlled member.

The ON time of the burner corresponds to the process conditions.

The control accessory is equippedped with a microprocessor that calculates the power requirements.

Different function versions are available.

TECHNICAL DATA

RZ-RS (Rekumat radiant tube burner)

 

Construction: Plastic housing with open terminals, alternatively with screw fastening (DIN 46121) or snap fastening
(mounting railDIN46277)
Dimensions: 150 x 70 x 112 mm (wxhxd)
Installation position: any
Auxiliary voltage: 115 / 230 Vac ± 10 % / 50 – 60 Hz
Power consumption: approx. 8 VA
Input: • Controllercontact(workingcontact):
The contact must be potential-free and is loaded with approx. 20 mA
• Analog input: Thermoelement NiCr-Ni with automatic reference point compensation
Output: 1 radiant tube burner connection (one changeover contact each for the solenoid valves “Gas” and “Air”).
The contacts are potential-free and can be loaded withamax.1A/max.250Vacor max.0,2A/125Vac, max.2A/30Vdc according to type.
Burner ON time in all-round operation: 30 s (adjustable between 23 and 37 s in case of overtemperature monitoring)
Air rinsing time: 2 s (adjustable from 1…2 s)
Overtemperature monitoring: Overtemperature adjustable from 1000…1200 °C, the gas valve is switched off and the air valve on after detecting overtemperature.
Power dosing: in ranges 850…1000 °C or 950…1100 °C
power reduction from 100% to 50% (quasi-continuous)
Perm.ambienttemperature 0…50 °C
