SPECIAL FEATURES:
- Connection to Rekumat burners (RB) or Rekumat radiant tube burners (RS)
- Screw type or mounting rail fastening
- Overtemperature input
- Power dosing input
- Adjustable burner on time
- Function display by LEDs
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) |
