The trip indicator is extinguished, the lists of alarms is erased and the device can Keys for access to measurements and alarm be closed. The reset key is disabled until the fault has been cleared. Each key provides access to a set of measurements according to the following method:.

Example: current measurement keys 3. When a measurement is not available in a type of Sepam, is displayed. This key provides access to step by step reading of the list of stored alarm messages. Pocket terminal socket 5 The previous message may be displayed by This socket is used to connect the TSM pocket terminal or the ACE pressing this key.

Display of: indicates the end of the list of alarm messages. Role of the keys: TSM pocket terminal b the pocket terminal beeps when the user presses a key that is disabled.

Your pocket terminal provides access b the menu key is used to display the previous menu, to all the Sepam information, such as: b the! A, kA, The pocket terminal beeps when it is connected. These lists are used when only a limited number of values may be used The main menu appears if nothing is displayed, for a parameter, e. A menu may comprise several pages. The first line always contains the name of the current menu or function.

Sepam is then in operation. Sepam is energized when operating normally. Sepam performs the functions of a precision measurement and alarm processing unit.

The values are displayed directed with the related unit A, kA, etc. The messages clearly worded. There are two ways of operating the device: b via the front face metering, annunciation keys , b via the TSM pocket terminals or PC using menu.

No value is displayed when the measurement is less than 1. Clearing measurements: b maximum phase current demand. A control monitoring N. TRIP1 P unbalance capacitor 1 tripping of the protections changes their prior status. Please refer to the information package provided by your installer. S26 LT A Sepam is energized. Setting of microswitches on the rear of the 21 20 device 19 18 Check that the microswitches. The microswitches must be set with Sepam 7 6 6 de-energized.

Commissioning b cartridge v Check that the cartridge is in its slot behind the Switch on the Sepam front wicket door. To do so, open the wicket door by After the Sepam has started up, check that no messages are present by pulling on the notch situated on the left side panel. Sepam S36 and S35 have a shield. Checking mode This shield is not another wicket door. Do not try All the data may be accessed for checking purposes without the risk of changing to open it.

Check that the cartridge has been parameters or settings. Check the tightening of the 2 threaded screws by hand. Parameter setting mode 2 Above all do not insert or remove the cartridge This mode is reserved for commissioning and maintenance. The first 5 characters in the first line indicate the Sepam model. Ensure that this model matches the Sepam model indicated on the side of Sepam.

It may be cancelled manually by pressing the Code key. Settings out of range. All events are set to zero by default.

This is an additional overcurrent protection function. The following types of time delay settings are available: definite, standard inverse, very inverse and extremely inverse. The following types of time delay settings are available: current sensor range rated current of network definite, standard inverse, very inverse and extremely inverse. CSP Earth fault current may be detected by: A 30 36 45 60 75 90 v three phase current transformers, A v a current transformer 1 A, 5 A combined with a CSH30 interposing ring CT, A v a specific CSH or CSH sensor according to the required diameter; 01 01 01 01 01 01 01 01 01 01 01 this is the most accurate method.

The two available ratings 2 A and 30 A provide a very wide setting range. SW2 Directional earth fault 67N This function has several uses: v highly sensitive earth fault protection for feeders supplied with power by a long cable high capacitive current , v quick, selective detection of upstream earth faults when there are several parallel substation feeders in the network.

This is an earth fault protection function. Overvoltage 59 Som1 Som2 Protection against abnormally high voltage and checking that there is sufficient v residual current measurement by core balance CT voltage for power supply changeover. This protection monitors system voltage U Thermal capacity used This protection is generally used for transformer is calculated according to a mathematical model, incomers or busbars.

The function comprises: Underfrequency 81 v an adjustable alarm setting, Detection of variances with respect to rated v an adjustable trip setting. This protection can be used for overall tripping v use the same setting for T1 and T2, or forload shedding.

Undervoltage 27 Breaker failure 50BF Protection used by automated functions changeover, Back up protection in the event that the incoming breaker fails to operate load shedding.

The function is ensured for single-phase and three-phase system voltages measured. This current indicates that the components This protection is used to prevent reclosing on live of one of the batteries are damaged. It monitors system voltage U Synchro-check 25 Allows closing of the breaking device if the two circuits have voltage, frequency or phase variances within the planned limits.

T2 cooling numeric keys 5 to mn time constant and units. Refer to the document entitled "testing", ref. For further information on the protection function characteristics,.

Program logic and annunciation Sepam has standard program logic for operation suited to the most current installations, it can be adapted for each application scheme by parameter setting at the time of commissioning. If your Sepam is customized, the role of the parameters may be different.
