7945724 - Commissioning Variomat Giga
Service description:
commissioning for a two-pump/compressor standard system in the Variomat Giga range by the customer service, comprising:
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.
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 the I/O and bus modules is not included in the scope of commissioning. Programming is charged separately according to time and effort.
commissioning for a two-pump/compressor standard system in the Variomat Giga range by the customer service, comprising:
- 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,
- All set values documented in a report.
- 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.
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
the service can take place within the local country inside about three weeks, internationally within about six weeks after placing of the corresponding order.

8997700 - I/O module GS
I/O module
Extension for Reflexomat, Variomat and Servitec control units.
Extension for Reflexomat, Variomat and Servitec control units.
With two isolating amplifiers for the analogue signals from pressure and level measurement. Six digital input contacts and six potential free output contacts for processing messages and alarms. All housed in a dedicated plastic casing for direct integration into the associated control unit or, optionally, for Wall mounting.
Detailed description:
- Digital input: – freely configurable, 6 inputs, of which 3 are normally open, 24 V internal potential, standard configuration, e.g. for external temperature monitoring, minimum pressure signal, manual make-up, and 3 as normally closed contacts, 230 V external potential. Standard configuration as normally open contacts, e.g. for emergency stop, manual mode for operation of Pump/compressor, manual mode for operation of overflow device.
- Digital output: - 6 freely configurable potential free change-over contacts, standard configuration, e.g. for signalling make-up water faults, minimum pressure not reached, exceeding the maximum pressure, or manual/stop operating mode.
All the above contacts can be freely configured by the Reflex service team in accordance with the available information.
Assembly: The plastic control cabinet housing can be fitted into the designated mounting space of the control unit, as an alternative to on-site Wall mounting or installation in other control cabinets.
Wiring to the control unit is also carried out on the part of the building site.
optional
8860200 - bus module Profibus DP
Bus Module
Bus module for conversion of the information such as operating status or variable network parameters from the control interface (RS 485) of Variomat, Reflexomat or Servitec with Control Basic or Touch controller into the data telegram.Everything in its own plastic housing for direct integration in the corresponding control unit or optionally for wall mounting.Installation:
Plastic switch cabinet housing can be inserted in the provided mounting slot of the control unit, as an alternative to 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
The cable connection to the microprocessor control unit includes its RS 485 interfaces and must be site-provided analogously to the power supply.On the Profibus side there is also an RS 485 interface with a baud rate of 0.96 - -1.5 Mb/s available. A sub-D cable plug must be made available on site. Remote control of the following functions and parameters from higher level building management system:
