INSTALLATION AND SETUP
b) For "latch" mode, wire the RESET and its associated COM terminal to the normally open
contacts of a switch, relay, or controller output. In this mode, when a fault condition
occurs, the relay drops out and the OVER or UNDER LED comes on. After the fault
condition is corrected, the contact must be momentarily closed to energize the relay.
5. If gap assess bypass is not selected (SW 5 OFF), a switch or contact may be connected
between AUXIN and COM to allow selection of two different calibration memories.
Calibration data is stored in the memory that is selected at the time calibration occurs.
Switching between calibration memories can be done at any time during DS1510 operation.
6. Optionally, the open collector FAULT output may be connected to a master system
controller or to an indicator that warns of error conditions within the DS1510 system. This
output is normally ON and turns OFF when an error condition is detected. Thus if the
DS1510 loses power, the FAULT output reports an error condition by default.
With firmware Version 3.6 and later (see Firmware Version at the end of this document),
the FAULT output turns OFF any time the DS1510 is not gauging the metal between the
probes. In addition to error conditions, setup (SU on the display) and calibration (CA on
the display) cause the fault output to turn OFF. This allows the unit to be monitored for
non-gauge conditions.
INITIAL SETUP
Probe and Gap Assessment
The startup process of the DS1510 commences immediately after power up and includes
several processes which are transparent to the user except for the sequence of characters that
appear on the two digit display.
When the unit first powers up, the several different sequences of characters may appear on the
two digit display depending upon which options are currently active. Typically, if probe gap
assessment is not bypassed, the startup display sequence includes momentary flashing of SU,
followed by momentary flashing of the probe identifier (PR 15, PR70, or PR 1H.), followed by
momentary display of the selected memory identifier, e.g. SL 01. When probe gap assessment is
bypassed (Switch 5 ON) the typical startup sequence includes momentary flashing of SU by,
followed by momentary flashing of the probe identifier, e.g. PR 70. If the probes are faulty,
disconnected, or cannot be identified, the controller flashes PR 01 indefinitely.
After the probes have been identified, the sensing system is characterized and the spacing
between the probes is determined. For this assessment there must be no material between the
probes. Switch 5 ON causes the controller to bypass this assessment unless a contact is closed
across AUXIN. However, it is essential that this process be completed at least once after
initial installation or whenever the physical arrangement of the probes is changed. If
assessment process is bypassed, the system flashes SU by on the two digit display during
startup.
When the operating conditions have been established, the two digit readout displays a numeric
value representing the receiver signal strength.
