1.2 SHORT DESCRIPTIONS OF APPLIANCE OPERATION

RB100: description

Robur Box RB100 device (Figure 1), interfaces the requests from one or more external control systems with GA and GAHP series Direct Digital Controller (DDC). It also provides for a valve activation service to be used by a DDC.

Figure 1 RB100

This appliance is provided with a four-figure display to both highlight a series of operation codes and view board operating parameters.

Parameters can be easily changed and/or set by proper knob (encoder) on the right side.

General features

RB100 interface device only operates if coupled with a Direct Digital Controller.

Before installing RB100 interface, DDC-firmware compatibility is to be checked, as

it must be equal or higher than FW 4.000.

Remember that DDC can support and manage up to 32 modules; a module is a machine able to produce refrigerated or hot water (e.g. an ACF 60-00 and an AY 00-119 are considered as two separate modules. See possible combination in table below).

Direct Digital Controller can manage several hot and/or refrigerated water production systems, especially:

1. No. 2 systems for simultaneous production of hot and cold water. Two ACF, AYF 60119/4 etc.-type units can be connected up to 16 “cold” modules and 16 “hot” modules

maximum.

2. No. 2 plants for alternate production (summer/winter) of hot and cold water. This is a

two-pipe plant, serving, for example, heating piping in winter and conditioning piping in summer. Up to max. 16 AYD 60-119/2 can be connected.

3. No. 1 system for producing refrigerated water only. Up to 16 ACF 60 maximum can be

connected.

RB100 : Installation and Use Manual

8 Ed. 06/2014 – FW version 1.002

4. No. 1 system for producing hot water only. Up to 16 AY 00-119 maximum can be

connected. The Direct Digital Controller (DDC) can be connected to two more DDCs maximum, to

control a 48 units (96 modules: 48 cold modules and 48 hot modules). Each DDC can be connected to 16 cold/hot units maximum (each one supporting 1 hot module and 1 cold module, for 32 total modules) or 32 units, with 16 hot and 16 cold maximum (always 32 total modules).

On a network consisting of the maximum number of installable modules, it is also possible to connect two extra modules, supported by RB100 interface. Each RB100 interface can manage two modules: one for request services, the other for valve service, described below (Paragraphs: Short descriptions of appliance operation; Service operation). For example: network consisting of the maximum number of installable modules + 1 RB100 where both modules are used, or network consisting of the maximum number of installable modules + 2 RB100 where service request module is only used for each one.

For each (cold and hot) module not available on the network, 1 RB100 can be added. For example, on a network with 3 DDCs and 47 cold/hot units (2 modules less of the maximum number allowed), 2 RB100 interfaces can be added, each one managing 2 modules.

In compliance with limits affecting the maximum number of configurable modules, 8 RB100 interfaces maximum can exist on the same network.

GA-GAHP SERIES: possible combinations Direct Digital Controller can manage ACF60 AY00-119-type modules, equipped with electronic boards S 60 and S 70, respectively. To calculate the number of units to be connected to the Digital Controller, RTCF and RTYF-series appliance are to be considered as follows:

- GAHP-A = No. 1 hot module

- GAHP-AR = No. 2 modules (1 “cold” + 1 “hot”)

- GAHP-W = No. 2 modules (1 “cold” + 1 “hot”)

- GA HR = No. 1 “cold” module

- ACF 60-00 = No. 1 “cold” module

- AYF 60-119/2 = No. 2 modules (1 “cold” + 1 “hot”)

- AYF 60-119/4 = No. 2 modules (1 “cold” + 1 “hot”)

- RTCF 120-00 = No. 2 “cold” module

- RTCF 180-00 = No. 3 “cold” module

- RTCF 240-00 = No. 4 “cold” module

- RTCF 300-00 = No. 5 “cold” module

- RTYF 120-119 = No. 3 modules (2 “cold” + 1 “hot”)

- RTYF 120-238 = No. 4 modules (2 “cold” + 2 “hot”)

- RTYF 180-238 = No. 5 modules (3 “cold” + 2 “hot”)

- RTYF 180-357 = No. 6 modules (3 “cold” + 3 “hot”)

- RTYF 240-238 = No. 6 modules (4 “cold” + 2 “hot”)

- RTYF 240-357 = No. 7 modules (4 “cold” + 3 “hot”)

- RTYF 240-476 = No. 8 modules (4 “cold” + 4 “hot”)

Short description of device operation

Connect appliance to a 24 Vac electric power supply line (paragraph 2.2 on page 25. When turned on, the appliance performs a series of internal tests to check proper software

and hardware operation, checks any set-up errors on operating parameters, shows an identification string (rb10, name of electric board) and, finally, keeps the leftmost decimal point flashing only.

This interface is used to collect requests (max 4 request for each RB100) for cold, hot and DHW services coming from external controllers where analogue and/or digital output signals are available; after collection, these requests are sent to DDCs which supply the relevant services.

Besides, interface has an auxiliary mode to connect any DDC-controlled valve, to separate or include the separable DHW group on the basic plant or switch a plant operating mode from hot to cold and vice versa.

Finally, there are digital outputs to signal any non-availability of request services (e.g. cold service not available as plant is switched on heating) and a general alarm output shared by all services, which always accompanies the non-available service and signal any other anomaly (e.g. valve anomaly).

RB100 interface device requires at least a Direct Digital Controller (DDC, see Figure 2). The switching between RB100 and DCC is performed by CAN network, (the same used for communication between DCC and machine).

In this case, for DDC use and configuration/programming instructions, refer to two

booklets: DDC Installation Manual (D-LBR 273) and DDC Use and Programming Manual (D-LBR 249).

DDC configuration/programming operations must be performed by Robur

Authorised Technical Assistance Centres (TAC) during first turning-on procedures and following manufacturer’s instructions.

Operation of services

As already said before, the interface device can receive, for each one of four services available, an analogue (0-10 V) or digital (clean contact) input signal. For each request received on input, the appliance sends a proper request to DDC; to this point, the Direct Digital Controller is in charge of machine management to meet such request.

The following services are available on each RB100 interface device:

Cold service: when an input signal is received on this service, the appliance provides for

a DDC request, so that DDC can control the turning-on of cold modules on the plant and properly manage them to meet such request;

Hot service: when an input signal is received on this service, the appliance provides for a

DDC request, so that DDC can control the turning-on of hot modules on the plant and properly manage them to meet such request;

DHW0 and DHW1 service: when an input signal is received on these services, the

appliance provides for a DDC request, so that DDC can control the turning-on of hot modules on the plant and properly manage them to meet such request. Especially, each service can be configured so that separable sanitary-type requests or basic plant sanitary –type requests can be made;

Valve service: this service is used to control three-way motorized valve, allowing for

management of hydraulic separation of unit separable from the basic unit or switching plant operation from heating to cooling and vice versa.

During the switching phase, the valves installed must ensure the minimum flow

specified in Table 3.

Operation of inputs for request services

One of the following types apply to each request service used:

Analogue input: this configuration allows receiving a 0-10 Volt input signal. RB100

interface sends to Direct Digital Controller a setpoint request proportional with input voltage. Thus, setpoint is provided for by RB100.

Digital input with local setpoint: this configuration allows receiving an input digital signal

(clean contact). When received on input, RB100 sends to Direct Digital Controller a setpoint request with a well-defined value, previously set in a proper interface parameter.

Digital input with remote setpoint: this configuration allows receiving an input digital

signal (clean contact). When received on input, RB100 only sends to Direct Digital Controller a turning-on request; the setpoint value to be used by DDC to meet such request is set on DDC itself [ref. to DDC Use and Programming Manual (D-LBR 249)].

RB100 : Installation and Use Manual

12 Ed. 06/2014 – FW version 1.002

Operation of valve service

As already said before, this service is used to control three-way motorized valves, which allow acting directly on hydraulic plant, mainly meeting one of the following two needs:

¾ manage hydraulic separation of separable unit from basic group; ¾ switch plant operation from heating to cooling and vice versa.

2 digital inputs support the valve, to connect valve auxiliary contacts (clean contacts to signal valve position). Position information is used by DDC [ref. to DDC Installation Manual (D-LBR 273) and DDC Use and Programming Manual (D-LBR 249)] to manage valves and the whole plant more accurately.

Water flow to be ensured by valves during their activation is specified in Table 3 on page

10.

Operation of outputs (general alarm, non-available request service)

RB100 interface has a general alarm output common for all services. It activates when error conditions occur on at least a service or when a DDC receiving a request service signals a machine or DDC warning/error.

For each service on RB100 interface, a digital output is available to signal service nonavailability. This service is only generated if service is enabled.

Service non-availability warning is always accompanied by an error code flashing on display, to identify abnormality (APPENDIX on page 72).

1.4 OPERATING TECHNICAL FEATURES

Input management

For each request service on interface (4 in total), according to input configuration (analogue/digital), RB100 sends turning-on or setpoint request to its DDC in different ways.

Input specifications only apply if service is active, otherwise no request is

transmitted to DDC:

In particular:

¾ Input configured as digital setpoint:

• the corresponding turning-on or setpoint request is sent to DDC if service contact status is “closed”;

• turning-off request is sent to DDC service if contact is “opened”.

Example of digital input management

For convenience, we refer to heating operation, but the same principle applies to all request services.

When hot service contact closes, the appliance sends a setpoint request to DDC, thus DDC manages hot units to meet such request.

• DDC turns on hot machines (if plant is switched to heating, otherwise non-available

service relay activates (APPENDIX);

• machines are operating: plant water heats up to setpoint temperature = +60°C;

• machines turn off: plant water, returning from line, gradually cools down to 50°C =

60°C – 10°C (setpoint + differential);

• DDC restarts the machines: plant water heats up again.

• The cycle repeats until the service contact corresponding to the request (in this case

the hot service) remains closed; if contact opens, the turning-off request reaches DDC and DDC-controlled units turn off.

RB100 : Installation and Use Manual

16 Ed. 06/2014 – FW version 1.002

If no request arrives from RB100, it does not mean that DDC-controlled units

remain off; this depends on the set-up of a specific menu on the Control Panel [ref. to DDC Installation Manual (D-LBR 273) and DDC Use and Programming Manual (D-LBR 249)] which allows system to operate with the only requests coming from RB100 or with the only DDC internal request or both.

¾ Input configured as analogue setpoint:

• Depending on input voltage value, turning-off or setpoint request is sent to Control Panel.

If input voltage is lower than -0.3 V or higher than 10.3 V, a proper out-of-scale

error code is displayed. (APPENDIX on page 72).

Example of analogue input management

For convenience, we refer to heating operation, but the same principle applies to all request services (attention: if plant operates in cooling, temperature is managed by the opposite logics).

• machines are operating: plant water heats up to setpoint temperature = +80°C;

• machines turn off: plant water, returning from line, gradually cools down to 70°C =

80°C – 10°C (setpoint + differential);

• DDC restarts the machines: plant water heats up again.

• The cycle repeats until the service input corresponding to the request (in this case

the hot service) has 10V voltage; if voltage decreases to 2.5V, no setpoint request reaches DDC and DDC-controlled units turn off.

• For each input voltage value between 2.5V and 10V, the corresponding setpoint (e.g.: 7.5V = +70°C) is sent to DDC, which controls machines to meet such temperature value.

Output management

Service non-availability is signalled:

¾ when a “permanent” non-availability exists, due to wrong configuration of Direct

Digital Controller (DDC), RB100 interface or abnormality on CAN communication;

¾ when a “temporary” non-availability exists, since service is not temporarily provided

for by DDC.

Permanent non-availability

Permanent non-availability is found in product installation and configuration phase, as problems can arise from firmware incompatibility between different products of the plant (DDC, RB100) or their wrong configuration.

This type of warning can remain after installation, due to problems arising from CAN communication between interface and Control Panel or single machine boards.

Temporary non-availability

Temporary non-availability is signalled in the following cases:

¾ for 2-pipe cooling/heating service: non-availability output activates when plant is

switching to an operating mode opposite to the current one, or when plant is turned to opposite from current request (E.g.: plant in cooling phase with hot service request from RB100: hot service non-availability relay activates);

¾ for basic plant DHW service to be only used when plant is operating in hot mode:

non-availability output is always active when the plant is switched to cooling or activated when the plant is switching to the operating mode opposite to the current one.

Non-available service output is always deactivated in the following cases:

¾ for basic plant DHW service also available when plant is cooling; ¾ for separable DHW.

(See APPENDIX on page 72).

GENERAL AND TECHNICAL FEATURES section

Ed. 06/2014 – FW version 1.002 19

Valve service

To manage valve service operation, valve service must be enabled and valve configured on Direct Digital Controller (DDC).

Each valve is controlled when RB100 receives from DDC a switching request (cold/hot or separable/basic). Now, RB100, after reversing, sends to Control Panel the status of limit switch auxiliary contacts, by which DDC can diagnose good or bad result of switching.

It has to be noted that valve operation does not depend on the existence of limit switch auxiliary contacts as possible configurations allow for using the valve service also with no limit switch auxiliary contacts.

Water flow to be ensured by valves during their activation is specified in Table 3 on page

10.

(See paragraph 5.7 on page 71)

If limit switch auxiliary contacts are used, the wrong status of their contacts

compared with proper valve position, originates an error signal by DDC, with specific flashing code, with immediate system shutdown.

(See APPENDIX on page 72).

2.2 APPLIANCE INSTALLATION AND CONNECTION TO POWER GRID

The appliance can only be installed by an authorized firm, complying with the

applicable laws of the installation country or by professionally qualified personnel.

Wrong installation or non-compliance with law can provoke damages to persons,

animals and things; Robur S.p.A is not responsible for damages due to wrong installation or non-compliance with law.

Before performing electric connection, ensure elements are not live.

Operations to properly install the appliance are listed below:

1. cut off voltage from electric panel where interface is to be installed to;

2. find, inside the panel, the area where RB100 board (9 modules) can be located;

3. install interface on DIN 35 mm guide (EN 60715).

Remember that appliance is equipped with knob, which must be easily accessible

without danger, its installation height must provide for easy display view.

4. Connect by 0.75-mm2 minimum section wires, as shown in Figure 9, respecting polarity.

Terminal 0 V is internally connected with GND terminal, then grounded; if

transformer used already has a grounded wire, it must be definitely connected to such terminal.

5. Complete all operations and close electric panel.

2.3 ELECTRIC CONNECTIONS FOR REQUEST SERVICES

Inputs

The electric installer must properly connect input of each service used, depending on its configuration, i.e.:

¾ analogue Input;

¾ digital Input.

In particular, it is necessary to underline again that each one of the 4 services can

be configured both as analogue and as digital; therefore, only one scheme for each one of the two types of connection, which can be applied to each service independently, will be represented here below.

Do not forget that jumpers on input terminal sides of service involved must be

properly located and service is to be properly configured (SECTION 5).

ELECTRIC INSTALLER section

Ed. 06/2014 – FW version 1.002 27

Analogue Input

For connecting the service as analogue input, we remind that the input voltage must range between 0 and 10 Vdc.

The maximum allowable length of the connection cables to the inputs of the request services is not less important and not to be neglected at all.

Max cable length (m) Cable section (mm²)

300 1.5 100 0.5

Given that the examples of cable length mentioned above are only two, in case of different cable section (in any case smaller than or equal to 1.5 mm²) you can calculate the maximum allowable length by using the following formula:

l = s × 200 where: l = length [m] s = section [mm²]

The cable must be shielded with the shield connected to earth at one end.

Maximum error of measurement, including the error due to the cable resistance:

± 40 mV (± 0.4% f. s.).

Connection Scheme

Table 7 - Legend of DDC connection schemes

Before any DDC fastening/connection operation, disconnect appliance power

supply by external isolating switch.

a. How to power supply Direct Digital Controller (DDC)

DDC needs low-voltage (24 V) power supply with 230/24 Vac, 50/60 Hz safety

transformer; minimum power necessary is 20 VA. The transformer must be located in a proper external panel, to be set by installed (see Figure 14). For connection, use a basic feature 2 x 0.75 mm2 cable.

How to power supply DDC from an external transformer

Have appliance disconnected from electric network

1. Set a 2-pole power cable (min. 2x0.75 mm

) and a 230/24 Vac. - 50/60 Hz safety

transformer with at least 20-VA power.

2. Remove DDC rear cover by untightening 4 fastening screws.

3. Insert power cable (DDC side) through the relevant opening in DDC cover and

connect as shown in Figure 14, respecting polarity:

TERMINAL 1 = 24 V TERMINAL 2 = 0 V TERMINAL 3 = GROUND

Ground on transformer terminal, connected to terminal 2 of DDC 4-pole connector.

Terminal 2 is internally connected with terminal 3, then grounded; if transformer used already has a grounded wire, it must be definitely connected to such terminal. Terminal 3 of DDC 4-pole connector must be safety grounded, in any case (r ≤ 0,1Ω).

4. When all operations are completed, close previously-removed DDC rear cover by tightening 4 fastening screws.

ELECTRIC INSTALLER section

Ed. 06/2014 – FW version 1.002 33

Figure 14 DDC power supply taken from external transformer to be set up by installer

If CAN-BUS cable has already been connected with DDC (procedure "c" described

below), be careful with 4-mm eyelet (or two eyelets) of CAN BUS cable shield: use fastening screws close to CAN-BUS socket (bottom right) to fasten eyelet (or two eyelets) as shown in Figure 17,on page 35.

DDC also consists of a buffer battery which, when power supply is cut off, can store

set values; buffer battery lasts for about 7 years and must be replaced

afterwards (contact Robur Authorised Technical Assistance Centre).

b. How to connect Direct Digital Controller (DDC) with RB100

Appliance and DDC communicate by CAN BUS network (Figure 15, on page 34). CAN-BUS network consists of a set of elements (appliances or DDC) named nodes,

connected by a cable (CAN-BUS cable), with 3 DDCs maximum.

8 RB100 interfaces maximum can be connected on the same plant (ref. to

Paragraph 1.2 on page 7).

Features of CAN-BUS cable are described below and specified in the relevant

Table 8.

Nodes can be final and intermediate.

A DDC and a RB100 can be located on any position of CAN BUS network: DDC and appliance can be indifferently located as final or intermediate nodes. Final nodes are appliances or DDCs connected with one single element. Intermediate nodes are appliances or DDCs connected with two more elements.

COMMISSIONING section

Ed. 06/2014 – FW version 1.002 45

SECTION 3 COMMISSIONING

This section provides the following information on appliance:

• Instructions necessary to Robur Authorised Technical Assistance Centre (TAC) for the whole commissioning procedure on appliance (see Paragraph 3.1);

The whole procedure for appliance commissioning provides for the performance of

the following (main) operating phases:

- preliminary checks on plant configuration;

- adjustment of plant operating parameters through RB100 and DDC.

Before operating as described in this section, the technician must read Paragraph

1.1 on Page 3.

The appliance must be connected to a DDC (version 4.000 or higher, configured as

controller); for control panel configuration phases, refer to two booklets about it.

RB100 : Installation and Use Manual

46 Ed. 06/2014 – FW version 1.002

3.1 COMMISSIONING PROCEDURE

The whole procedure for appliance commissioning is to be performed by a Robur

Authorised Technical Assistance Centres only (TAC) following manufacturer’s instructions. Warranty could be void if procedure is not performed by TAC.

Appliance proper operation and duration depend on its proper usage:

• proper installation;

• proper use.

When released from factory, the appliance is reliable and tested.

To properly perform the whole commissioning procedure on appliance, act in the following order:

- preliminary checks on plant conformity;

- adjustment of RB100 and DDC operating parameters;

- adjustment of plant operating parameters depending on user’s needs.

Preliminary checks on plant conformity

Robur TAC must:

¾ check that the whole plant has been implemented as designed, following

manufacturer’s instructions and under standards enforced (Project must be drawn by a certified professional);

¾ personally check that (hydraulic/gas and electric) Robur external units on the

plant have been properly performed:

¾ personally check that (electric) connection of RB100 and DDC interfaces (as well

as their connections to external units) have been properly performed;

¾ check that plant compliance condition really exist (as stated by authorized firm in

charge of installation to the user).

The Declaration of Conformity CERTIFIES that the plant complies with standards

enforced.

It is a compulsory document, thus, authorized firm in charge of appliance

installation must issue it to the owner, under the Law.

If all the above-listed conditions apply, the TAC can operate the appliance “commissioning”.

COMMISSIONING section

Ed. 06/2014 – FW version 1.002 47

In case of plant non-compliance found during preliminary checks, the TAC could decide not to operate the appliance “Commissioning”.

If so, Robur TAC must:

¾ warn any installation abnormality to user/installer;

¾ warn any situation, dangerous for appliance and persons, to user/installer;

¾ warn any lack in appliance documents;

¾ considering warnings issued, indicate any corrective operations on plant to be

performed by installer in order to operate the appliance “Commissioning”.

The user/installer must perform any corrective operation on plant as required by

TAC. After corrective operations by installer, TAC must assess the plant again. Now, if TAC identifies plant conformity and safety conditions, it can operate for commissioning.

Dangerous plant situations for persons and appliance.

Should one of the following situations arise, no commissioning is performed by TAC:

- appliance installed in unsuitable area (e.g. outdoor, not in safety electric panel)

- appliance installed in such conditions preventing safe access and operations;

- situations arising from appliance defects or malfunctions during its transport or installation;

- all situations arising from non-compliant plants and considered (after on-field assessment) as potentially dangerous.

Abnormal plant situations.

Should one of the following situations arise, TAC, upon its discretion, can perform commissioning, but appliance remains off until manufacturer’s conditions are restored:

- installations (potentially non dangerous) not performed at best, non complying with national and local standards enforced;

- installations (potentially non dangerous) not performed at best, non complying with manufacturer’s instructions;

- installations possibly implying appliance malfunctions.

RB100 : Installation and Use Manual

48 Ed. 06/2014 – FW version 1.002

Adjustment of main operating parameters

To operate appliance commissioning, the operations below must be performed according to the sequence specified.

• Access to panel where appliance is installed.

• If off, turn on RB100 from power switch set by installer upstream of it.

To adjust operating parameters of the whole plant:

• refer to SECTION 5: BOARD SETTINGS for parameter setting on RB100 interface.

• refer to DDC manual for setting parameters of control panel.

Configuration of Direct Digital Controller (DDC): for adjustment of plant operating

parameters depending on user’s needs, refer to “DDC Use and Programming Manual (D-LBR 249)” delivered with it.

When turned on for the first time, an operating code could appear on RB100

display (and/or on DDC display). If operating code is issued by RB100, see the list of codes in APPENDIX on page 72; if operating code is issued by DDC, se the list of codes in "DDC Installation Manual (D-LBR 273)" (delivered with it).

The positive result of commissioning only CERTIFIES proper operation of

appliance (and DDC). It does CERTIFY plant compliance with standards enforced.

RB100 devices do not need special maintenance, except for normal cleaning at

regular intervals.

USER INTERFACE section

Ed. 06/2014 – FW version 1.002 49

SECTION 4 USER INTERFACE
