Two channels, proximity input, 10kS2 input impedance
2 00mV/mil (8V/mm) with 3300 or 7200 with 5mmi8mm probe
100 mV/mil (4V/mm) with 7200 with 11mm/14mm probe
Full scale meter range selected per Option Table.
±0.33% of full scale error typical at 77F (25°C)
±1% of full scale error maximum at 77°F (25°C)
See Table 1 On Following Page
Alert/Danger alarm levels (adjustable from 0 to 100% of full scale)
Alarm delay times are user-programmable per options, plus time delay of signal
averaging
LCD bargraph, dual scale with outside scales marked per monitor full scale fre-
quency range and center scale marked for probe gap voltage at 1.6% resolution.
Green LEDs annunciate transducer O K condition, red LEDs annunciate
DANGER , ALERT , and BYPASS conditions.
Response time is user selectable, See Table 2 on following page
Front panel switches (3) for reading
ALERT
and DANGER setpoint levels, and for
reading probe Gap voltage
Switches on circuit board for setpoint adjustment, Danger Bypass, Channel Bypass
and thrust direction
External remote controls: Reset, Inhibit, and setpoint adjust (T and l )
Output proportional to selected full scale monitor range and protected against con-
tinuous short circuit to ground:
+ 4 to + 20mA, 12 V compliance
+ 1 to + 5 Vdc, 100-ohm output impedance
0 to -10 Vdc, 100-ohm output impedance
-24 Vdc or -18 Vdc determined by transducer option selected in power supply,
short-ciruit protected
Relay drives for alarms (ALERT and DANGER) and monitor transducer OK
