computer MAX 2.2.- STARTING SCREEN When the computer MAX is started (just after supply connection) the screen shows a code indicating the device version. It’s important to indicate this code in case of reporting any device fault or error. 2.3.- DEFINITIONS In this section we shall give several definitions which will be useful to understand several sec- tions of this manual. 2�3�1�- FOUR QUADRANT REGULATORS This term is used to describe the regulators which are able to perform measure and control, either if the active power flows from the utility to the customer network (the common case of a consuming facility) or if it flows in the reverse sense. The later is the case of facilities containing... -

computer MAX Program 1:2:4 � The rated power of the second stage is twice the rated power of the first stage and the rated power of third stage and up is 4 times the power of the first stage. For instance, a 5-stage device of 300 kvar would be formed by a first stage of 20 kvar, a second stage of 40 kvar and 3 equal stages of 80 kvar, and would be described as a device of (20 + 40 + 3 x 80) kvar. Other switching programs� Other switching programs are also commonly available, like 1:2:2:4 or 1:1:2:2, etc. Abbreviated designation form, as can be deduced from previous cases, consists of a sequence of numbers giving the relationship between the different stage powers (kvar), and the first stage power, which value is taken as device (1). The successive stages will be designated by 1, or 2 or 4, etc. meaning that the kvar ratio of such stages with regard to first stage are equal, twice, four times, etc. 2�3�5�- PLUG &... -
Page 10: 3�- Product Description
MAX 3�- PRODUCT DESCRIPTION The power factor regulators, of types computer MAX 6 and MAX 12 measure the cos φ (some- times called Displacement Power Factor, DPF) in a supply network and control the connection and disconnection of power capacitors in order to regulate such parameter. -

The measured voltage exceeds the rated voltage by a +15%. 5.4.- ALARM RELAY In case that the number of stages configured in a computer MAX 6 or MAX 12, is less than 6 or 12 respectively, the relay number 6 or 12 is automatically configured as alarm relay. The relay remains connected in absence of alarm (positive safety) and disconnects in case that one or more of the errors listed in section occur. -

computer MAX 5.5.- REGULATOR STATUS AND KEY FUNCTIONS computer MAX regulators have two possible status. Normal or RUN Status: This is the normal working status of the regulator. In such status the device measures and displays the cos φ of the loads and automatically regulates the connec- tion and disconnection of capacitors in order to compensate according to programmed target value. - Page 18 computer MAX Tabla 9 (Continuation): Key functions in set-up status� Function Downwards navigation in the menu options available in the set-up menu.

computer MAX 6�- CONFIGURATION 6.1.- CONFIGURABLE PARAMETERS In order to adapt the regulator to the loads, certain parameters of the Computer MAX must be set-up. The programmable parameters, the required settings and the set-up procedure are ex- plained here below. See also paragraph to see “5.5.2.- KEY FUNCTIONS IN SET-UP STATUS”... -

computer MAX 6�1�2�- COS φ TARGET To set-up this parameter, use the keys until the cursor points to the option , then push The parameter allows the setting of the desired PF in the installation. The regulator will control the connection of the necessary number of capacitors to get the maximum approach to the target value. -
Page 21: 6�1�4�- C/K Parameter Calculation
computer MAX IMPORTANT: If C/K is adjusted too low the system will connect and disconnect steps with a lower threshold and therefore the number of operations to control the average PF will be higher. If C/K is adjusted slightly above the required value (10%) the system will react with higher threshold values and therefore the number of operations to control the average PF will be lower. -
Page 22: 6�1�6�- Connection And Re-Connection Time Settings
This setting allows the selection of the number of stages of the PF compensation equipment. Depending on the device type, computer MAX 6 or MAX 12 we can select up to 6 or 12 stages. If the number of stages is less than 6 or 12 respectively in computer MAX 6 or MAX 12 the relay number 6 or 12 is automatically assigned as alarm relay. -

computer MAX 7�- RUN STATUS Once the device has been configured according to installation needs it can be set to RUN mode to regulate the PF of the installation. RUN mode is the default mode after exiting the set-up menu or after the device start (supply connection followed by a short initialisation period). When the device is in RUN mode it can reach one of the following status: A�- Normal RUN status (Absence of alarm): In this status the device performs the automatic PF regulation, connecting and disconnecting the capacitor stages according to installation needs. -
