AMETEK 1746 LDT Interface Card - Manual (Page 9)

5 Installation & Programming Manual
Chapter 1: Introduction & Overview
Non-Volatile Memory
The non-volatile memory on the 1746L card is provided in the form of EEPROM. Because this
is not battery backed memory, no battery maintenance is required. The user can save the 1746L
LDT Interface Module configuration to EEPROM. The “Save Configuration”, Command 6, is
used to do this.
NOTE: The EEPROM on the 1746L is only guaranteed to 10,000 write cycles. Because of this
it is recommended that this command be used sparingly.
Configuration
There are two versions of the board. The first version will support one LDT and one input. The
second version will support two inputs and two LDTs. The LDT type and the input configuration
need to be programmed through the backplane by the user.
The Monitor’s operating status is indicated by the two (2) LEDs on the face panel.
RUN The green LED indicates that the card is operational.
FAULT The red LED indicates there is a card fault, or when there is a transducer fault.
There are four typical causes for a transducer fault:
1. Broken LDT cable
2. Improperly wired cable
3. Faulty LDT
4. Non-compatible LDT
