Measurements The specific measurement area will activate in the Measurements - Synchrocheck menu if the Ekip
Synchrocheck module is detected correctly by Ekip Touch.
Measurement Description
• Ok = Synchronism conditions fulfilled
Module
• Not Ok = Synchronism conditions not fulfilled or function disabled
• Ok = Synchronism condition regarding frequencies fulfilled
• Not Ok = Synchronism condition regarding frequencies not fulfilled or synchronism
Frequency function disabled, or frequencies outside measuring range limits.
• --- = Synchronism condition regarding frequencies not available (example: for
operation with dead busbar)
• Ok = Synchronism conditions regarding voltages fulfilled.
Voltage • Not Ok = Synchronism conditions regarding voltages not fulfilled or synchronism
function disabled
• Ok = Synchronism condition regarding phase difference fulfilled
• Not Ok = Synchronism condition regarding phase difference not fulfilled or
Phase synchronism function disabled, or frequencies outside measuring range limits
• --- = Synchronism condition regarding phase difference not available (example: for
operation with dead busbar)
• Voltage measured by Ekip Synchrocheck given in Volts
• .... = measurement DC or less than 1 VAC
Ext Side Voltage (1)
• --- = measurement not available (example: because synchronism function is
disabled)
Voltage measured on internal sockets, given in Volts.
Int Side Voltage (2)
• .... = measurement less than 1 VAC
Frequency measured by Ekip Synchrocheck
Ext Side • --- = measurement not available (example: because synchronism function is
Frequency (1) disabled, or operation with dead busbar, or frequencies outside measuring range
limits)
Frequency measured on internal sockets
Int Side • --- = measurement not available (example: because synchronism function is
Frequency (2) disabled, or operation with dead busbar, or frequencies outside measuring range
limits)
Phase difference between voltages, given in degrees
• --- = measurement not available (example: because synchronism function is
Phase Difference (1)
disabled, or operation with dead busbar, or frequencies outside measuring range
limits)
• Busbar active = with automatic detection of operating mode and operation with
active busbar, or with synchronism function not enabled
• Dead bar = with automatic detection of operating mode and operation with dead
Auto detection
busbar
• --- = Measurement not available (example: owing to manual detection of operating
mode)
• Vint ≤ Vext = Internal voltage the same as external voltage or lower
• Vin > Vext = Internal voltage higher than external voltage
Voltage relation
• --- = Measurement not available (example: because the synchronism function is
disabled, or direct voltages or voltages lower than 1 V).
• fint ≤ fext = Internal frequency the same as external frequency or lower
• fin > fext = Internal frequency higher than external frequency
Frequency relation • --- = Measurement not available (example: because synchronism function is
disabled, or operation with dead busbar, or frequencies outside measuring range
limits)

(1) voltage difference measurement accuracy is ± 10% unless the parameter value is 0.02 Un, in which case
accuracy is ± 20%
(2) the characteristics of the voltage and frequency measurements coincide with those given on the internal
sockets (page 110)
