Verifying Operation
Verify the operation of the PTR by observing the two LEDs. During Test Mode, listen for
the buzzer to indicate Tag detection. Table 3 and Table 4 list the LED and buzzer
signals and the corresponding operations and states.
Low Power Mode
If main power fails the PTR will enter Low Power Mode.
Low power mode is indicated by the following:
 The green LED is off; and,
 The red LED is flashing approximately once every 1.5 seconds.
In low power mode the PTR does not generate a LF field. The PTR transmits a “Device
in Low Power Mode” message to the network approximately once every 12 seconds.
The PTR remains in this mode until main power is restored or until reserve power is
exhausted. Reserve power should last for at least 15 minutes. When main power is
restored the PTR will begin normal operation.
Table 3: Power and LF Field States
LED and Buzzer Power and LF Field State
Buzzer emits short beep. Power up.
Green LED slowly flashing. Power on and LF field off.
Green LED on continually. Power on and LF field on.
Red LED briefly flashes once
every 1.5 seconds.
Main power has been lost. See Low Power
Mode on page 9.
Table 4: Tag Identification Operations
LED and Buzzer Operation
Red LED flashes Tag identified, network message sent.
Red LED flashes with buzzer beep Test Mode tag identification. A network
message is NOT sent.
Red LED continually emitting brief
flashes. Every 12 seconds, a longer red
LED flash occurs and the buzzer beeps.
Error: The PTR has detected one of three
error conditions. See “Troubleshooting”
on page 8.

Standby Mode
In Standby Mode the LF field is triggered on for 10 seconds when the input contacts
are opened or closed. The PTR identifies and reports tags while the LF field is on. After
10 seconds the LF field shuts down until the next input trigger.
Select Standby Mode by setting the Mode Switches to 0, 1, 0 as in Figure 6.
Input Wiring
The input is an active low so that when the input terminal is grounded the input is
active or on. Wire the input to one terminal of a switch. Wire the other side of the
switch to either ground terminal on the PTR 4 pin wiring connector.

Figure 8: Alternate Input Wiring
End Of Line Input in Standby Mode
The End-Of-Line (EOL) setting enables input fault or input tampering detection.
An EOL input provides two fixed resistance values instead of open and closed switch
states. The PTR will treat the transition from one resistance value to the other as an
opening, or as a closing switch. If EOL resistors are installed and the EOL input is
enabled, the PTR will remember the input values resulting from the EOL resistors.
1 0 1 Duty Cycle 3 The LF field cycles on for 10 seconds and off for 30
minutes automatically. The PTR identifies and reports
any tags found while the field is on.
