Product details

Reflexomat
Pneumatic and control module for compressor-controlled Reflexomat pressurisation station for pressurisation and for make-up water control in sealed heating and chilled water systems.Constructed in compliance with DIN EN 12828 and the requirements of VDI 4708, with CE marking.

Functional unit comprising a pneumatic part and a Control Touch operating unit. Both are ergonomically combined in an easy-to-maintain modular floor-standing framework system made of EV 1 anodized aluminium precision sections and with CE marking. In the pneumatic part, the pressurisation is implemented using a compressed air compressor in conjunction with a compressed air solenoid valve as an overflow device.

A safety relief valve is included to act as a pressure safeguard for the RG primary tank or RF secondary tank. The system pressure is measured with an electronic sensor.In the pneumatic part, the pressurisation is implemented using two compressed air compressors in conjunction with a compressed air solenoid valve as an overflow device. The system pressure is measured using an electronic sensor. Pneumatic part comprising:
  • Compressed air compressors
  • Type-tested air solenoid valve
  • Type-tested safety valve, for pressure protection of the diaphragm - expansion tank
  • Electronic pressure sensor
  • corresponding connection lines
The Control Touch operating unit with TFT colour display inclusive of communications electronics is integrated in a panel-type rugged plastic housing and mounted directly on the control unit with a horizontal alignment. An optional separate and vertical wall mounting plate at maximum three metres distance from the power electronics is possible. Communication electronics comprising:
  • 4,3" resistive colour touchscreen for programming, operating documentation and monitoring as well as provision of help texts for all functions
  • Two RS485 serial interfaces as data and/or communication interfaces
  • Serial TTL-interface with two connection terminals for connection of 2 IO-boards
  • Potential-free output for forwarding of the collective message
  • Two electrically isolated analogue outputs e.g. for system pressure
  • Input for the evaluation of contact water meters
  • Slot for a compact bus module, one SD card, e.g. for data read-out, software updates, etc.
  • 230V output for connection of level-dependent makeup/degassing stations
The power electronics are installed in a dedicated plastic control cabinet which is mounted directly below the operating unit. Power supply is via a main switch. Featuring in detail:
  • Main switch on housing exterior
  • Compressor control
  • Cable management for external connections
  • Mounting slot for optional control unit modules completely assembled and wired ready for connection according to VDE regulations
Control Touch is a fully automatic and freely programmable microprocessor control with touchscreen operation, real-time clock, differentiating error and parameter memory, combined graphical and clear-text display of system pressure, tank level and all relevant operating and fault messages, functional diagram, signalling of the active operating mode, collective fault message, low water level, functioning of the compressors, air solenoid valve and make-up valve.

Functioning of the pressurisation in the limits +/- 0.1 bar including compressor monitoring. Controlled make-up, automatic interruption and fault message upon exceeding of the runtime and/or the number of cycles. Evaluation option provided by a contact water meter including optional possible capacity monitoring of ion exchangers in the make-up pipe. Documentation and control of the entire system in respect of the above mentioned parameters.
Constructed in compliance with DIN EN 12828 and the requirements of VDI 4708, with CE marking.

7945630 - Commissioning Cat. 2

Service description:
commissioning category 2 for a standard system in the product ranges Reflexomat, Variomat in ranges -2 and -4 incl. primary vessel and water make-up unit by the customer service, comprising:
  • without travel and departure expenses,
  • Adjustment of system to the operating parameters specified by the client,
  • Checking the settings and operating parameters, and the system's performance and function in the overall system,
  • Fillsoft and Fillset are checked too
  • All set values documented in a report.

Requirements:

  • electrical and hydraulic connection of the control unit, the accessory components and filled supply system.
  • The expansion vessels of the pressurisation station must not be filled with water.
  • A sufficient supply of filling water must be provided.

Customer benefits:
While it is entirely possible for customers to put a recently purchased system into service themselves, there are a number of reasons why commissioning by Reflex is a better idea.

  • Certainty that the system is set up for optimum operation
  • Excluding of possible damage due to incorrect commissioning thus reliability and avoidance of time and costs for downtimes

Commissioning date:
the service can take place within the local country inside about three weeks, internationally within about six weeks after placing of the corresponding order.
Services provided by Service are net! The price does not include any site waiting times or work arising from improper installation or improper condition.
Programming of the expansion and bus modules does not form part of commissioning. Programming is billed separately based on time and expenditure.

8860000 - bus module Lonworks Digital

Bus-Module Lonworks Digital
Bus module for conversion of the digital message(s) from the microprocessor controls Control Basic or Touch of Variomat, Reflexomat or Servitec into the Lonworks Digital data telegram.

The cable connection to the Control microprocessor controller takes place over its potential-free contacts and must be site-provided analogously to the power supply. On the LonWorks side there is an interface with FFT-10 A Transceiver .

Other digital messages can also be converted in conjunction with the I/O module (option).

Installation:
Plastic switch cabinet housing for on site wall mounting or installation in other switch cabinets.

The wiring to the control unit is likewise performed on site. Commissioning and wiring does not form part of the scope of delivery.
