Short Control; Cross Mode; Cross Range; Trigger Source - Ametek Amrel PLA Series Operation Manual

SHORT CONTROL

Enables/Disables Short Control.

CROSS MODE

Toggles between Input Off/Input Remain. Input remain will allow input to remain on when switching modes.

CROSS RANGE

Toggles between Input Off/Input Remain. Input remain will allow input to remain on when switching ranges.

TRIGGER SOURCE

Select the trigger source for transient operation. Please refer to the following table for different trigger sources and the
available triggering methods

AMREL eLoad provides programmable OVP/ OCP/OPP and UVP/UC P/UPP over-limit and under-limit protection
capabilit ies. The user can program all the protection values and delay times. Protection will be activated once the
protection mode has been tripped and then shut down the eLoad input.
programmed delay time to accommodate short duration surges without inadvertently shutting the input off.
Protection Sub-Menu Navigation: Press the "Menu/Local" key then turn the  encoder to select the PROTEC TION
function then the "ENTER" key. Turn the  encoder to select the appropriate protection or delay function by pressing
the "ENTER key to display the current value. Press the "ENTER" key to edit or enter the new value then press the
"ENTER" key to confirm entry. Press the "CLEAR" key to exit from the PROTECTION MODE sub-menu.
V-ON (Under Voltage Lockout): To p revent the eLoad from operating under unstable conditions such as voltages
below the minimum operating voltage, the V-On Protection feature can be utilized. The V-On protection will force the
input to remain off until the V-On voltage threshold is exceeded, the purpose is to ensure sufficient voltage is delivered to
the eLOAD for normal operation. When operating under strict turn -on sequences, such as sending power v ia a power
supply into an eLOAD with the input already turned on, current overshoot, bounce or rin gin g may occur. As a
