Peak Picker PSEL Functions
Peak Picker Signal Conditioning selection activates the PSEL Peak Function menu. This menu is used
to adjust Peak Picker functions necessary for obtaining the peak measured temperature value. These
functions must be adjusted to match the process for proper operation.
External Switch Control of Track and Hold Operation
The Modline 5 has provisions for a remote process controlled input switch be wired to the Violet and
Violet/White twisted wire pair of the Sensor’s interconnecting cable. If Track and Hold signal
conditioning is selected, the switch input is required to change from Track temperature operation
(switch open) to Hold mode (switch closed) as required in the process system.
Wiring and switch operation for the Track and Hold feature are described in Section 4

PSEL – Peak Picker Functions
The PSEL Functions are for Peak Picker Operation. Refer to Section 8
a description of Peak Picker signal conditioning operation including these functions
5.10.1
D.R. – Decay Rate Function
The Decay Rate range is 0.00 to 300.00°F or 0.00 to 166.66°C per second depending on Fahrenheit or
Celsius unit’s selection. The Decay Rate must be set to retain peak measured temperature value and
ignore momentary decreases in measured temperature caused by process conditions. The goal is to
eliminate erratic measurements due to gaps in workpieces, bursts of smoke, or steam, etc. in the sight
path of the Sensor while allowing the peaked value to decay down to lower process temperature values
as they occur.
Sensor Firmware Version Operation Summary
Original Sensors with firmware versions less than 1.02 have unit-less degree units that
range 0.00 to 300.00 for both F and C unit’s selection. The instructions provided on the
next page are for Sensors with firmware versions 1.02 and higher.
DPM – Digital Panel Meter Interface firmware version operation:
For DPM Interfaces with firmware versions 1.2 used with Sensor firmware version less than 1.02. Sensor
set for °C, DPM will read, but not enter values higher than 166. Sensor can be set to 300.
Sensor set for °F, DPM and Sensor are compatible.
For DPM Interfaces with firmware versions 1.1 used with Sensor firmware 1.02 and higher:
Sensor set for °C, DPM will read or enter values to 300. Sensor can be set to 166.66 maximum.
