Functional Description

3.1 Brief functional description
®
The DULCOMETER
The measured variables to be processed are:
- pH/chlorine
- pH/ORP
- pH/pH
- Chlorine/chlorine
3.2 Mechanical design
®
The DULCOMETER
3.2.1 Control panel installation in accordance with DIN 43700 (96 x 96 mm)
The DULCOMETER ®
with the format 96 x 96 mm, depth 140 mm. In this installation arrangement, the device is completely
integrated in the control panel or installed in a housing. The device is electrically connected directly via
terminals at the rear.
The terminals as well as an SN6 socket for pH input project beyond the rear panel.
Retaining brackets for mounting the device in the control panel are provided on the housing.
The display pc-board with the graphic display is located at the front. It features 6 operating buttons and a
transparent display window.
3.2.2

Wall mounting

®
The DULCOMETER
(control panel installation kit, Part No. 79.29.08). The durable plastic housing is made up of an upper
section and lower section. The graphic display and transparent display window are accommodated in the
upper section while the lower section houses the processor, power supply and options board. The
connection to the display is made by means of a ribbon cable. Electrical connection is made via the
originally closed, punch-out cable leadthroughs on the underside of the housing. On devices with an SN6
input (dependent on identity code), the standard SN6 socket is located on the left-hand side. A wall
mounting bracket is provided at the rear of the device to facilitate simple wall mounting.
3.3 Electrical design
The device processes an input signal while taking into consideration disturbance variables and operator
inputs. The result is displayed and made available to other devices via a standard signal.
When equipped with corresponding actuators, the device can undertake control functions. It is designed
to activate metering pumps, solenoid valves as well as mA standard signal. The activation variable is
recalculated every second.
The controller does not feature a separate power switch. It is therefore immediately ready for operation
after being connected to the power supply.
The devices correspond to relevant requirements concerning electrical operating equipment. For this
purpose, the following standards are complied with:
• Supply voltage in accordance with - DIN IEC 38
• Electrical safety in accordance with - EN 61010-1
• Emitted electromagnetic interference in accordance with - EN 55011 Gr. 1/Cl. A
