Locked Mode: cell [092E] Setting Values are locked to the same value for all interfaces. All interfaces have the same value for [092E]. Whichever interface selects Locked Mode will have its setting for [092E] applied to all interfaces. Any interface can then change [092E] and it will apply on all interfaces.

Reset Life Hours 37 88 0 hr 1 hr to 300000 hrs step 1hr

Reset Life Hours is zero, so that when the commissioning of the thermal element is over, the loss of life statistics calculations
are reset to zero. For old transformers this setting should indicate how much life the transformer has already lost; therefore, it
should be set to the transformer loss of life

P643 and P645 only.
Determines whether any phase or all three phases must satisfy the undervoltage criteria before a decision is made
V<1 Function 42 04 DT IDMT or DT or Disabled
P643 and P645 only.
Tripping characteristic for the first stage undervoltage function. The characteristic is defined by: t =  K / (1 – M)
Where:

V<1 Poledead Inh 42 08 Enabled Enabled or Disabled
P643 and P645 only.
If the setting is enabled, the relevant stage is inhibited by the pole dead logic.  This logic produces an output when it detects either an open circuit breaker through auxiliary contacts feeding the relay opto inputs, or it detects a combination of both undercurrent and undervoltage on any one phase.  It allows the undervoltage protection to reset when the circuit breaker opens to cater for line or bus side VT applications.
V<2 Status 42 09 Disabled Enabled or Disabled
P643 and P645 only.
Enables or disables the second stage undervoltage element

VT SUPERVISION 46 01 Sub-Heading Sub-Heading
VT Supervision does not apply to P642 when the optional three-phase VT input is available. Only visible if Main VT is fitted or P642 model with 2 VT inputs.
VTS Status 46 02 Indication Blocking or Indication or Disabled
Determines whether on detection of VTS.
• VTS logic is Disabled.
• VTS alarm is Indication only.
• Voltage-dependent protection elements are Blocked. Optional conversion of directional overcurrent to non-directional protection (blocking mode only).
VTS Reset Mode 46 03 Manual Manual or Auto
VTS block is latched after user-settable VTS Time Delay. Once latched, the reset methods are: Manual using the front panel interface (or remote communications).
Auto provided VTS condition has been removed and 3-phase voltages have been restored above ph
VTS Time Delay 46 04 5s 1s to 10s step 0.1s
Operating time delay setting of the VTS element on detection of a voltage supervision condition.
VTS I> Inhibit 46 05 10 0.08pu to 32pu step 0.01pu
The overcurrent setting inhibits VT supervision if all 3-phase voltages are lost, due to a close-up 3-phase fault after CB is closed.
In P643, CT1/CT2/CT3 if the VT is in the HV, TV or LV. In P645, CT1/CT3/CT5 if the VT is in HV, TV or LV.
VTS I2> Inhibit 46 06 0.05 0.05pu to 0.5pu step 0.01pu
NPS overcurrent setting inhibits VT supervision if a fault occurs with excess negative sequence current. In P643, always referred to CT1/CT2/CT3 if the VT is in the HV, TV or LV.
