Only dashes displayed, time is not displayed
Model: Levo and Classic Series Digital Clocks and Timers
Symptoms
All or some of the symptoms may be present.
lDigital Clock/Timer only displays dashes and time is not displayed.
Problem
Digital Clock/Timer is not receiving a signal from the Transmitter.
Analyze
1. Determine if cause is due to Transmitter broadcasting schedule and/or clock signal search frequency.
Digital Clock/Timer signal search frequency: every 10 minutes on the 5's (5, 15, 25, 35, 45, 55 minutes) of the hour, a clock's
receiver turns on to search for a Transmitter signal to receive a time update.
Transmitter with External Antenna: were the clock(s) installed between the 7th and 38th minute of the hour? Clocks receive a
time signal and update their time the 39th minute of the hour. If the Transmitter is not in an error mode, power the down the
Transmitter, wait 30 seconds, and power back on. A power cycle forces the Transmitter to broadcast for eight consecutive
hours.
Broadcast (Transmit) Schedule Transmitter with Internal Antenna: broadcasts its synchronized time continuously to the
system clocks and devices.
Digital Clock/Timer signal search frequency: every 10 minutes on the 5's (5, 15, 25, 35, 45, 55 minutes) of the hour, a clock's
receiver turns on to search for a Transmitter signal to receive a time update.
2. Identify scope of clocks experiencing issue - single clock or all clocks/clocks in specific area.
Single clock
a. Reset the clock to initiate a manual signal search: press and immediately release the button located in its setting panel.
Levo Series - from the back side of the clock remove the small rectangular access panel. Setting changes can be made
while the clock/timer is ON and changes will take effect within a few seconds.
All clocks/clocks in specific area: verify the Transmitter(s) is not in an error state. If multiple Transmitters on site, start with
the Master Transmitter and then proceed by verifying the other units.
6XR Levo Series Digtial Clock & Timer Troubleshooting Guide

a. Is the Transmitter's red LED flashing and/or is information displayed on its front display not correct? If yes, the
Transmitter is an error state that may result in the clocks not receiving a broadcasting signal. Resolve the issue by
completing the troubleshooting topics for the Transmitter model. Once the Transmitter is in a normal state and
broadcasting, clocks correct at their next scheduled update.
3. If a clock(s) continue not to set its time, it may be due to the signal coverage at the install location or area.
Perform a signal check: take the clock with the issue to a known good signal area where clocks are set to the correct time
with a solid colon. Apply power to the clock experiencing the issue. Press and release the clock's reset button in its setting
panel. If the clock sets to the correct time, it’s a signal issue at the original installation location .A reset causes the clock to
scan for a broadcasting Transmitter frequency.
4. If a clock(s) in a specific area continues not set its time, it may be due to interference preventing a clock from receiving a
broadcasting signal.
NOTE
When certain types of electronic light ballasts become defective they may radiate broadband noise, which can
interfere with wireless devices. While interference issues are unlikely with the Primex system, high levels of noise
present in the 72-76MHz range could potentially cause clocks which are located far from the Transmitter and also
within the close proximity of these ballasts to not receive a signal. Very limited instances have occurred in the past,
which has only been found to happen when ballasts become defective.
Solution
1. Determine if Transmitter broadcast schedule or clock signal search frequency is cause of clock not updating its time.
2. Single clock: reset clock to search for signal.
3. All clocks/clocks in specific area: check Transmitter status and resolve any issues.
4. Verify signal coverage at install location or area.
5. Verify no interference at install location or area - defective ballast.
If the issue cannot be resolved, additional troubleshooting is required. For further assistance, contact Primex Technical Support at
1-262-729-4860.

One or more LED segments are not illuminated (appear dark)
Model: Levo Series and Classic Series Digital Clocks and Timers
Symptoms
All or some of the symptoms may be present.
lOne of more LED segments are not illuminated (dark).
lAll LED segments are not illuminated.
Problem
Segment may be burned out or power trouble on the circuit board.
NOTE
First digit is not illuminated from 0:01.01 to 9:59.59 in 12 or 24-Hour configuration.
Analyze
Initiate a reset.
1. Either power cycle the clock or initiate a manual reset.
Levo Series - from the back side of the clock remove the small rectangular access panel. Setting changes can be made while
the clock/timer is ON and changes will take effect within a few seconds.
A power cycle or manual reset causes the clock to scan for a broadcasting Transmitter. The clock initiates its power cycle/reset
sequence as described below.
1. All LED segments display 8s with a red dot on the bottom right of each of the two hour digits and one at the second or last
minute digit.
2. All LED segments display dashes and then dashes with a colon between the hours and minutes.
3. Once the clock/timer receives a signal from the Transmitter, the LED segments display the time received from the Transmitter
and a flashing red dot appears at the bottom right of the second hour digit for three minutes.
Solution

Symptoms
All or some of the symptoms may be present.
lThe colon between the clock hour and minute is flashing.
lThe clock's time may not be accurate.
Problem
The clock has not received a signal from a Transmitter for more than 3 days.
Digital Clock/Timer signal search frequency: every 10 minutes on the 5's (5, 15, 25, 35, 45, 55 minutes) of the hour, a clock's
receiver turns on to search for a Transmitter signal to receive a time update.

Displays 13:15 and Not Updating to Correct Time
Symptom
Clock displays 13:15 and is not updating to the correct time.
Cause
13:15 is a Primex code that represents the number of digits and clock's firmware version. The cause of this issue is due the clock is
not seeing a signal from a Transmitter.
Solution
1. Check the status of the Transmitter(s) to be sure they have the correct information on its display and red LED is not flashing.
Once the Transmitter is broadcasting, clocks will correct at their next scheduled update.
Digital Clock/Timer signal search frequency: every 10 minutes on the 5's (5, 15, 25, 35, 45, 55 minutes) of the hour, a clock's
receiver turns on to search for a Transmitter signal to receive a time update.
2. Does Transmitter have an External Antenna? During troubleshooting, you can power-cycle a Transmitter with an External
Antenna to allow it to broadcast continuously for 8 hours.
Broadcast (Transmit) Schedule Transmitter with Internal Antenna: broadcasts its synchronized time continuously to the
system clocks and devices.
Broadcast (Transmit) Schedule Transmitter with External Antenna: broadcasts its synchronized time to the system clocks
and devices from the 39th to the 6th minute of the next hour and changes to a standby mode during the 7th to the 38th
minute of the hour (standard broadcast schedule). During initial power-up, the Transmitter broadcasts for 8 consecutive
hours. After the 8 hour power-up period, the Transmitter reverts to its timed broadcast schedule.
3. Reset the clock. A reset causes the clock to scan for a broadcasting Transmitter frequency.
From its setting panel, press and release the Reset button - from the back side of the clock remove the small rectangular
access panel. Setting changes can be made while the clock/timer is ON and changes will take effect within a few seconds.
4. There is also a potential the clock is experiencing interference and not allowing the clock to receive a broadcasting signal.
Move the clock to an area where other clocks are set to the correct time. This task should isolate the issue to either a defective
clock or signal issue.
NOTE
When certain types of electronic light ballasts become defective they may radiate broadband noise, which can

interfere with wireless devices. While interference issues are unlikely with the Primex system, high levels of noise
present in the 72-76MHz range could potentially cause clocks which are located far from the Transmitter and also
within the close proximity of these ballasts to not receive a signal. Very limited instances have occurred in the past,
which has only been found to happen when ballasts become defective.

Code Blue Event Fails to Trigger
Problem
A Code Blue Event Fails to Trigger.
Cause
A Code Blue Timer is a multifunction digital clock and timer that integrates with an existing Code Blue system to effectively time
each event.
lWhen a Code Blue event is invoked, a relay/pulse is sent from the Code Blue system to the Code Blue Timer, which triggers it to
begin counting up.
lIf a Code Blue event is in effect, it will take priority and the timer’s previous task will run in the background until the Code Blue
event ends or is stopped.
lA switch control allows the user to operate the timer in multiple modes.
lIn the event of a power outage, the timer's memory maintains the correct time for up to one hour.
Solution
Assistance from the Code Blue System provider may be needed to resolve this issue.
1. Inspect the wiring from the Code Blue Timer to the Code Blue System. Wiring is determined by the Code Blue System as
specified below. T he supplied 4-pin connector integrate the Code Blue System to the Code Blue Timer.
lCode blue systems that apply a voltage to start a code blue event: wire the timer 4 pin connector's RED (Positive Code Blue
Input) and BLACK (Negative Code Blue Input) wires to the code blue system. Cap off the WHITE and GREEN wires separately.
An input voltage of 5-120V (AC or DC) can be used. When using DC, be sure to use the correct polarity; RED wire is positive
and the BLACK wire is ground. Code Blue start and stop events are triggered by the application of voltage across the code blue
input wires.
lCode blue systems that use a dry contact and do not inject a voltage: wire the timer 4 pin connector's GREEN (Ground) and
BLACK (Negative Code Blue Input) wires together and wire the WHITE (12VDC) and RED (Positive Code Blue Input) wires to the
code blue system dry contact.

Elapsed Timer count-up or count-down fails to trigger
Symptom
lElapsed Timer count-up or count-down does not trigger when initiated from Timer Control Switch.
Problem
There may be an issue with a cable connection, wiring issue, or a defective Timer Control Switch.
Analyze
1. Inspect the Timer Control Switch for any damage or degradation.
2. Check the cable from the Elapsed Timer to the Timer Control Switch for any damage or degradation. Cable may need to be
replaced.
lLevo Series Elapsed Timer: cable is a RJ11 flat telephone cable (straight wire configuration).
3. Loosen the screws on the membrane Timer Control Switch. The screws may be over tightened, causing the issue.
4. Swap the Timer Control Switch with a known good switch to isolate the issue to the switch itself or a potential wiring issue
between the Timer Control Switch and the Elapsed Timer.
Solution
1. Inspect Timer Control Switch.
2. Verify cable connections.
3. Loosen screwed on membrane Timer Control Switch.
4. Swap Timer Control Switch.
If the issue cannot be resolved, additional troubleshooting is required. For further assistance, contact Primex Technical Support at
1-262-729-4860.

Programmable Timer is Not Counting Down Per its Schedule
Problem
Programmable Timer is not counting down.
Cause
For Programmable Timer models, the timer's schedule is configured in the Primex Event Scheduler Pro software to the schedule
ID controller 24. The schedule is downloaded from the Event Scheduler Pro to the system Transmitter, allowing the Transmitter to
broadcast the schedule. This issue may be due the timer setting, the schedule download to the Transmitter(s), or the Transmitter
status.
Solution
1. From its setting panel, verify the PT/TC Switch (5) is set to the ON position.
At access the setting panel - from the back side of the clock remove the small rectangular access panel. Setting changes can
be made while the clock/timer is ON and changes will take effect within a few seconds.
2. From the Primex Event Scheduler Pro software, verify the schedule ID is set to controller 24.
3. Verify the schedule has been downloaded the local Transmitter(s) that are within range of a Programmable Timer.
4. Verify the Transmitter operating status. Refer to the Transmitter Troubleshooting topics.
If the issue cannot be resolved, additional troubleshooting is required. For further assistance, contact Primex Technical Support at
1-262-729-4860.
