CP-Touch

EASYLAB operating unit type CP-TOUCH

The CP-TOUCH control panel is used to display and operate the ventilation and safety functions of a fume cupboard or an entire room control system. The user receives information about the status of the fume cupboard or room and can switch between various operating modes and functions. The display and operating elements in detail:

• Variant CP-TOUCH 4.3
  Touch display with a diagonal of 4.3", resolution
  of 480 × 272 pixels and a colour depth of 65k
• Alarm sounder
• 3-colour function display shows the safe operation of the fume cupboard or a room
• Warning display and area for messages
• Status area for displaying active functions
• 5 function groups with configurable functions contained therein
  • Actual and setpoint displays for current values
  • Operating modes
  • Additional functions
  • Settings such as time, date, display settings, language
  • Timer
• With service socket

The range of functions of the control unit can be configured with the EasyConnect configuration software and in part directly adapted on
the CP-TOUCH to the project-specific requirements. The range of functions may vary for different fume cupboards or rooms. The touch display is used for display and operation. The available functions are shown on the display surface by corresponding symbols. The user selects the desired function on the touch display, e.g.

• Select operating mode
• Activate automatic sash device
• Fume cupboard lighting on/off

In the current values area, the user can see actual and setpoint values for volume flow rate, face velocity, opening height of the sash or, on the room controller, the room pressure or the total volume flow rate for extract/supply air (only if the necessary sensors are available). In addition, the display also shows system messages and pending alarms and messages.
CP-TOUCH also has a real-time clock for showing the current time on the display. This function also enables the parameterisation of a time programme with an interval of 7 days. This allows 5 switching points per day with the available operating modes to be set directly on the control unit.

Application

• Displaying and operating the aerodynamic functions of fume cupboards
• Status display according to EN 14175
• Connection to fume cupboard controller EASYLAB TCU3
• Two control panels per fume cupboard controller possible, e.g. for fume cupboards with sash windows on two sides

Functions

• Signalling of operational reliability for fume cupboards according to EN 14175

• Maximum sash distance monitoring according to EN 14175

Possible displays

• Values for volume flow rate setpoint and actual volume flow rate

• Face velocity actual value and setpoint value (fume cupboards with face velocity transducer, equipment functions FH-VS and FHVD)
• Simultaneity limit has been exceeded
• Service is due
• Power supply failure (EASYLAB controller with expansion module EM-TRF-USV)
• Smoke extract function
• Fume cupboard overtemperature for high temperature fume cupboards according to EN14175, measured with optional
• temperature sensor as accessory

Configurable functions

• Operating modes

• Lighting control
• Control of an automatic sash device
• Real-time clock for timer with an interval of 7 days: 5 switching points per day for fume cupboard operating modes

Operating modes

• Standard volume flow (daytime operation)
• Increased volume flow (emergency operation)
• Reduced volume flow (night-time operation)
• Shut-off (night-time operation, system shutdown)
• Open position (emergency operation, full ventilation)
• Manual control (permanent override of central settings)
• Increased volume flow and manual operation can also be time-limited

Status display

The fume cupboard controller monitors the required volume flow rate and, depending on configuration, the face velocity. A relevant deviation is transmitted by the 3-colour function display. If the volume flow rate is too low, an acoustic alarm is sounded.

• Green: Normal operation
• Red: Alarm, volume flow too low
• Yellow: Note, volume flow too high
