Brief functional description
The control module delta® enhances the delta® range of pumps to
become measurement variable-dependent metering pumps. The
control module delta® has an active 4-20 mA input for use in combi‐
nation with pHV1, RHV1 measuring transducers or chlorine
sensors CLE-mA. The control module delta® uses PID control
behaviour to adapt the delta® solenoid metering pump precisely to
the requirements of the process. If a two-sided control is required,
a second pump can be controlled via the optional pacing relay.

Assembly
The bypass fitting (flow gauge) used depends particularly on the
measured water, in some cases also from the measured variable
or or the combination of the measured variables. The type DGMA
with flow controller is always used for all clear water types and the
type DLG III for contaminated water is also used for upstream flow
controlling.
Hydraulic connection, pipework
With the DGMa, the hydraulic connection of the measured water is
carried out using an 8 x 5 mm hose connection. A shut-off ball
valve is installed before and after the bypass fitting. The optionally
available measuring water filter is installed before the bypass
fitting. Each of the bypass fittings have a mounted sampling cock.
4.2
Hydraulic test run after installation
A hydraulic test run of the measuring / control station is necessary
after successful installation.
n The sampling cock must be closed! Otherwise measured water
will escape
n Check all screw connections before the initial commissioning
n Open the shut-off ball valve on the inlet and outlet ends.
n The system must now be hydraulically tight. No fluid must leak
out.
If fluid should leak out, the reason for this must be determined and
eliminated.
4.2.1

Setting the limit values
Hysteresis
An hysteresis is installed here so that when in the
range of the limit value of the control module delta® ,
switching is not constantly carried out between the
control and base load metering.
The hysteresis is approx. 2% of the measuring range:
–
(„Limit value up“ minus „Limit value down“) * 2 %
You have the possibility of setting the permissible value for the
controlling for each sensor type. When a measurement value lies
outside this limit value, the control will be discontinued. Basic load
control is only active in this case.
If the measurement value lies outside the limit value than a
warning is reported and the symbol ! is displayed in the status

Determine the dead time and adjusting the checkout
time
Each controlled system has a dead time. The dead time is the time
that the controlled system requires to determine a change caused
by the addition of the metered chemicals by measurement.
You have to select the checkout time greater than the dead time.
You can determine the dead time by allowing the the metering
pump to operate in manual mode and, e.g. metering acid.
NOTICE!
Dead time determination
You should only determine the dead time when the
actual process cannot be influenced in a negative way
by the manual metering.
You have to determine the time that the controlled system (there‐
fore, the entirety of the controller, sensor, measured water, flow
gauge, etc.) requires to detect the first change to the measured
value, from beginning the metering. This time is the „Dead Time“. A
safety margin must be added to this determined dead time, e.g.
25%. This safety margin must be determined individually for your
process. If the set value is not reached after the checkout time has
elapsed, see Ä Chapter 6.8 „Setting the set value“ on page 29, the
metering pump switches to base load metering.
If the control module delta® should not have reached a certain
threshold after the checkout time, the control module delta®
switches to base load operation. A warning is released to the supe‐
rior system, the delta® solenoid metering pump in this case and the
is displayed in the status display of the delta® solenoid
