Vfd Grundfos Direct Sensor; Pwm Interfaces; Data Communication / Bus - Resol DeltaSol CS Plus bidirectional Manual For The Specialised Craftsman

Note
It must be possible to disconnect the device from the mains at any time.
Î Install the mains plug such that it is accessible at any time.
Î If this is not possible, install a switch that can be accessed.
Do not use the device if it is visibly damaged!
The power supply of the device must be 100 ... 240 V~ (50 ... 60 Hz). Attach flexible
cables to the housing with the enclosed strain relief and the corresponding screws.
The controller is equipped with 2 semiconductor relays to which loads such as
pumps, valves, etc. can be connected:
Relay 1
18 = Conductor R1
17 = Neutral conductor N
13 = Protective earth conductor ⏚
The mains connection is at the following terminals:
19 = Neutral conductor N
20 = Conductor L
12 = Protective earth conductor ⏚
Connect the temperature sensors (S1 to S4) to the corresponding terminals
with either polarity:
1 / 2 = Sensor 1 (e. g. collector sensor 1)
3 / 4 = Sensor 2 (e. g. store sensor 1)
5 / 6 = Sensor 3 (e. g. store sensor top)
7 / 8 = Sensor 4 (e. g. return sensor)

VFD Grundfos Direct Sensor™

The controller is equipped with 1 input for a digital VFD Grundfos Direct Sensor™
for measuring the flow rate and the temperature. Connection is made at the VFD
terminal (bottom left).
2.4

PWM interfaces

Speed control of a HE pump is possible via a PWM signal. The pump has to be con-
nected to the relay as well as to one of the PWM outputs of the controller. Power
is supplied to the HE pump by switching the corresponding relay on or off.
Made in Germany
The terminals marked PWM 1 and 2 are interfaces for bidirectional HE pumps.

Data communication / Bus

The controller is equipped with the RESOL VBus
supply to external modules. The connection is to be carried out at the terminals
marked VBus (either polarity).
One or more RESOL VBus
• DL2 / DL3 Datalogger
• KM1 Communication module
Furthermore, the controller can be connected to a PC or integrated into a network
via the RESOL VBus /USB or VBus
