RMTXX1 Series - IntelliPoint RF™ Instruction Manual
2.6.2 Time Delay Action
2.6.3 Failsafe
2.6.4 Current Output Assignment
2.6.5 Manual Certify
Time delay action describes whether the relay contacts are
delayed from going into the alarm state or recovering from an
alarm state.
• FWD: Delays system from coming out of alarm.
• REV:Delays system from going into alarm.
• Instrument is supplied with TIME DELAY action set in
forward mode (FWD) position.
• Time delay action is field-selectable using jumper
located on sensing element/circuit board side of
housing.
"Failsafe" describes the level condition that causes the
transmitter to go into alarm.
• The Failsafe is field-selectable using a jumper located on
the sensing element/circuit board side of the housing.
• High Level Failsafe (HLFS) is the condition when the probe
is covered, the unit is in alarm.
• Low Level Failsafe (LLFS) is the condition when the probe
is uncovered, the unit is in alarm.
• The instrument is supplied with the failsafe jumper set in
high level (HLFS) position.
The Output Current can be configured using the jumpers as
follows:
• Jumper on pin #1 and #2:
8mA - Alarm, 16mA - Normal, 22mA - Fault
• Jumper on pin #2 and #3:
8mA - Normal, 16mA - Alarm, 5mA - Fault
The Manual Certify (High Level Fail Safe Only) test feature
performs a confidence test of the system by duplicating the
same signal as a high-level alarm condition without requiring
the system to be removed from the tank.
Simulating a high level with the Manual Certify feature:
•
Forces unit into an alarm condition.
The Manual Certify test is initiated with the press of the
Manual Certify button located on the sensing element/circuit
side of the housing. After pressing the button, the green LED
flashes for 5 seconds and the red LED illuminates. The output
is moved to the alarm condition for 2 seconds. If the red LED
does not light, and the loop current does not move to the alarm
condition, the Manual Certify test has detected a fault. Consult
the trouble-shooting section of this Instruction Manual.
