Operation
Modline 5
101
Sensor set for °F, DPM and Sensor are compatible.
5.10.2
RSET – Manual Peak Picker Reset
Performs a manual Peak Picker reset. The Peak Picker Reset “clears” the stored peak information. The
Sensor begins to measure temperature in the Peak Picker mode again after a manual reset.
5.10.3
External Switch for Remote Peak Picker Reset
The Modline 5 has provisions for a remote process controlled input switch to be wired to the Violet and
Violet/White twisted wire pair of the Sensor’s interconnecting cable. If Peak Picker signal conditioning
is selected, the remote switch can enable or disable the Peaking action. With no switch or the switch
maintained in the open position, Peaking action is enabled. With the switch closed, peaking action is
disabled and the Sensor continuously indicates actual temperature variations as they occur.
A momentary closure of the switch resets the Peak Picker function to the current temperature reading.
The peaking action begins again when the switch returns to the open position.
Wiring and switch operation for the Peak Picker are described in Section 4
5.10.4
AUTO – Auto Peak Picker Reset
With Peak Picker On, the Auto Peak Picker Reset function will cause a Reset when the measured
temperature matches or is below the selected Reset Below temperature. As long as the measured and
displayed temperature remains below the selected temperature, the Peak Picker remains in reset
condition and the Sensor continuously measures and indicates temperature without any peaking
picking action.
This function is affected by the Response Time function. It is possible for a long response time to delay
a Reset triggered by the Reset Below temperature even though the target temperature has decreased.
5.10.5
RBEL – Reset Below Temperature
Automatic Peak Picker Reset must be on for this function to appear in the menu. Sets the Reset Below
Temperature that causes Automatic Peak Picker Reset with the Peak Picker On and Auto Peak Picker
Reset On. When the target temperature matches or is below the selected value, Automatic Peak Picker
Reset will take place and the Sensor indicates temperature without any peaking action.
5.10.6
DEL – Peak Picker Delay
Peak Picker signal conditioning may be delayed. The Peak Picker Delay time is selectable in the range
of 0.01 to 10.00 seconds. Its primary use is with the Auto Peak Picker Reset and Reset Below Temperature
functions. The Peak Picker Delay function is used to delay the start of the peaking action for up to 10
seconds following the detection of the leading edge of a new target. See Section 8
page 129 for a detailed explanation.
It has limited operation when used with Peak Picker signal conditioning without the Auto Peak Picker
Reset function. It will provide the selected delay after any Peak Picker Reset. The reset can be from the
Sensor rear panel, a reset from a momentary closure of the Peak Picker Reset external switch or a reset
from the RS485 PR command.
