The following rules must be followed when connecting cards to each other and to the application: Check ratings for valve stated in the manufacturer's manual. Loads that exceed the maximum limits set forth herein must not be applied to outputs; When connecting loads, follow connection diagrams carefully; To avoid electric pairings, wire all low SELV utilities separately from high voltage ones. Before connecting the valve, configure driver appropriately by selecting the type of valve from the compatible ones. IMPORTANT! Make sure the machine is switched off before working on the electrical connections. The operations must be carried out by qualified personnel. To ensure proper connections, comply with the following: Power supplies other than those specified can seriously damage the system. Use cables of suitable section for the terminals used. Separate the cables of probes and digital inputs from inductive loads and high voltage connections to prevent any electromagnetic interference. Do not place the probe cables near other electrical equipment (switches, meters, etc.) Make connections as short as possible and do not wind them around electrically connected parts. To avoid causing static discharges, do not touch the electronic components on the boards. The device must be connected to a suitable transformer that complies with the specifications provided in the Specifications chapter Power supply - high voltage outputs (relay) Do not exceed the maximum permissible current; in case of higher loads, use a contactor of adequate capacity. Temperature probes Attention! Make sure the power supply voltage complies with that required by the instrument Analogue inputs-probes The temperature probes have no characteristic insertion polarity and can be extended using standard bipolar cable (note that extending cables can affect the performance of the device in terms of electromagnetic compatibility: take great care with the wiring). Pressure probes Attention! Pressure probes have a specific insertion polarity which must be observed. Signal cables (temperature/pressure probes, digital inputs, TTL serial) must be wired separately from high voltage cables. Eliwell-supplied probes are recommended. Contact Eliwell sales department for item availability. TTL MFK KEYB Serial connections Use a 5-wire TTL cable up to 30 cm in length. An Eliwell-supplied TTL cable is recommended.

29 <IMG INFO> 208,45 204, , OPERATING MODE is a controller for electronic expansion stepper valves which regulate the minimum overheating value at the exit point from the evaporator. The regulation value is the percentage opening of the valve, which is converted into a valve output percentage value based on the following parameters: de10 - Maximum valve opening percentage is the maximum opening of the valve. de14 - Minimum valve opening percentage is the minimum opening of the valve. de15 - Maximum valve useful opening percentage is the maximum useful opening of the valve. If the regulator commands an output greater than or equal to de15, the real output will equal de10. N.B.: If de15 <de10 the function is ignored. If the regulator commands an output less than or equal to de14, the real output will be equal to 0. If the regulator commands an output greater than or equal to de10 for a longer time than de13, the maximum valve opening alarm Er08 is generated to signal a critical system condition such as insufficient load, undersized etc... N.B.: to disable the signal, set de13=0. % real output 100% de10 % request de14 de15 100% Set saturation calculates the real overheating value using the two analogue dai3 overheating and dai1 saturation inputs. Via a PID type controller, it modulates valve opening so that overheating reaches the de32 setpoint. The algorithm is dynamic: the actual value of the overheating may not reach the setpoint or drop below it temporarily. It this causes liquid to escape from the evaporator, the value of Setpoint de32 will have to be raised. N.B.: valid for de30=1 de21 system type PID configuration parameters will be loaded automatically from the device by selecting the type of system defined in parameter de21. MOP (Maximum Operating Pressure) For MOP regulation, a threshold can be defined in pressure setpoint de52. If this threshold is exceeded for a time greater than de53, a MOP alarm will be generated (see Er07). MOP regulation can be enabled in parameter de50. MOP regulation can be disabled at switch-on or on resetting after a defrost condition for the time set in de51. 29/60

33 10 PARAMETERS (PAR) Parameters are used to configure every aspect of ; They can be modified with: The Multi Function key (MFK) Keys on remote SKP 10 terminal Personal computer and Device Manager software The following sections analyse each parameter, divided into categories (folders), in detail. Each folder is designated with 2 figures (example: df, UI, etc). Folder label Acronym meaning (label) Parameters of: dl Driver local configuration I/O configuration df Driver protocol configuration Protocol configuration de Driver valve configuration Valve configuration Ui User interface User interface When not indicated otherwise, the parameter is always visible and modifiable, unless customised settings have been configured via serial. NB: parameters and folder visibility can both be controlled (See Folder table). If folder visibility is modified, the new setting will apply to all parameters in the folder. Levels of visibility Four levels of visibility can be set by assigning suitable values to each parameter and folder, by serial, software (DeviceManager or other communication softwares) or by programming key. The visibility levels are: Value 3 = parameter or folder always visible. Value 2 = manufacturer level; These parameters can only be seen by entering the manufacturer's password (see parameter Ui28) (all parameters specified as always visible, parameters that are visible at the installation level, and manufacturer level parameters will be visible). Value 1 = installation level; These parameters can only be viewed by entering the installation password (see parameter Ui27) (all parameters specified as always visible and parameters that are visible at the installation level will be visible). Value 0 = parameter or folder NOT visible. 1. Parameters and/or folders with visibility level <>3 (i.e. password protected) will only be visible if the correct password is entered (installer or manufacturer) following the procedure outlined below. 2. Parameters and/or folders with visibility level =3 are always visible and no password is required; in this case, the procedure below is not required Parameters / visibility table, folder visibility table and client table The tables below list all information required to read, write and decode all accessible resources in the device. There are three tables: - The parameter table contains all device configuration parameters stored in the non-volatile memory of the instrument, including visibility information - The folders table lists the visibility of all parameter folders - The client table includes all I/O and alarm state resources available in the volatile memory of the instrument. Description of columns: FOLDER LABEL VAL PAR AdDRESS This indicates the label of the folder containing the parameter in question. This indicates the label used to display the parameters in the instrument's menu. The whole part represents the address of the MODBUS register containing the value of the resource to be read or written in the instrument. The value after the point indicates the position of the less significant data bit in the register; if not indicated it is taken to be zero. This information is always provided when the register contains more than one information item, and it is necessary to distinguish which bits actually represent the data (the working size of the data indicated in the column DATA SIZE is also taken into consideration). Given that the modbus registers have the size of one WORD (16 bit), the index number after the point can vary from 0 (least significant bit LSb ) to 15 (most significant bit MSb ). Examples (in binary form the least significant bit is the first on the right): VAL PAR AdDRESS DATA SIZE Value Content of register 8806 WORD ( ) 8806 Byte ( ) 8806,8 Byte ( ) 8806,14 1 bit ( ) 8806,7 4 bits ( )
