Introduction

AllSync Plus Clock Installation & Operation Manual

The AllSync Plus Clock Manual explains how to install AllSync Plus Clocks and understand their operation.

The American Time AllSync Plus clock is the second generation of the AllSync Chameleon clock.

The AllSync Plus clock incorporates all of the first generation AllSync clock features with improved accuracy and

15 minutes of reserve power for short power outages.

FEATURES

• 5 Year Warranty

• Microprocessor controlled movement

• 15 minutes of backup power (no batteries required)

• Accuracy to within ±1 second of a consistent master clock

• Reduced power consumption

• Diagnostic LED

DESCRIPTION

The american time ® AllSync Plus clock is designed to work with multiple master clocks and correction signals.

This unit is programmed to identify the signal it receives from the master and operate as that style of clock.

Changing clock operation from one style to another is as easy as unplugging the clock from one system and plugging it into another. If needed, changing the placement of 2 small jumpers on the circuit board can change the voltage required to run this clock from 120vac to 24vac or 24vac to 120vac. This clock provides 15 minutes of backup run power without the use of batteries. If a power outage should last longer than 15 minutes, the clock will synchronize to the master clock at the hourly and 12 hour correction cycles.

CORRECTION SIGNALS

Works on:

• Hourly correction: 7-9 seconds starting at the 57th minute and 54th second. 12 hour correction: 13-18 seconds starting at 5:57:54 (am and pm).

• Hourly correction: 24-28.5 seconds starting at the 0 minute and 0 second. 12 hour correction: 24-32 minutes starting at 6:00:00 (am and pm).

• *Hourly correction: 54-56 seconds starting at the 58th minute and 5th second. 12 hour correction: 10 pulses of

94-96 seconds starting at 5:05:00 (am and pm) and repeating every 120 seconds.*

• Hourly correction: 24-26 seconds starting at 0 minute and 0 second. 12 hour correction: 25 pulses of 24-26 seconds starting at 6:00:00 (am and pm) and repeating every 60 seconds.

• Hourly correction: 63-67 seconds starting at the 58th minute and 0 second. 12 hour correction: 14 pulses of 63-

67 seconds starting at 5:06:00 (am and pm) and repeating every 120 seconds.

• Hourly Correction: 28.75-35 seconds starting at the 59th minute and 30th second. 12 hour correction: 13 minutes and 52 seconds-18 minutes and 8 seconds starting at 5:12:00 (am and pm). *Note: Standard Electric version part number required for this correction type.

n Note: When switching between these correction protocols, you must use a different correction protocol to complete the transition. The AllSync Plus clock needs to distinguish between hourly corrections before it can change correction protocols internally.

Startup Routine

AllSync Plus Clock Installation & Operation Manual

LED

LED location on back of clock

The AllSync Plus clocks operate differently from their fixed clock protocol mechanical counterparts and from the older AllSync clocks.

After power is initially supplied to the AllSync Plus clock run line, the following will occur:

1. The clock will charge its internal backup power cell and undergo startup diagnostics.

Note: This may take from 1-9 minutes. During this charge period the clock will run through the start

up diagnostics indicated by the LED on the back of the clock and the clock hands will remain still.

2. The green flashing LED indicates the microprocessor is telling the movement what time it is. The default time for the circuit board is 12:50. This is the time the movement receives on startup and after extended power outages (greater than 15-20 minutes).

3. The LED will turn solid red.

Note: The solid red LED indicates the clock circuit board has not received a 12 hour correction.

4. The clock will rapidly advance to the microprocessor time.

Note: Rapid advancement may last as long as 10 minutes. Total rapid advancement time depends on hand location prior to startup.

5. The clock will stop rapid advancement sometime between 12:50 and 1:15 as seen on the clock face and begin running at the correct pace (1 tick per second).

6. The movement will receive the hourly correction 2.5 minutes after the microprocessor receives the hourly correction from the master. The clock hands will then rapidly advance to match the minutes and seconds on the master clock connected to it.

Note: If a master does not send a valid correction, the AllSync Plus clock cannot synchronize its minutes

to the master.

Note: The minute and second hands will be on time with the master after this rapid correction.

7. Approximately 2.5 minutes after the conclusion of the first 12 hour correction from the connected master the AllSync Plus clock will rapidly advance to match the exact time on the master (hour hand

will correct).

Note: The AllSync Plus clock is set up at the factory for clock code 01 (xx:57:54 – 8 second hourly

correction, 5:57:54 – 14 second 12 hour correction). If running a different clock protocol, the AllSync

Plus clock may require an additional 12 hour correction to recognize the different clock protocol. If this

is the case, allow 24 hours for the clock to synchronize.

General Operation

AllSync Plus Clock Installation & Operation Manual

AllSync Plus accuracy

The AllSync Plus clock will be ±1 second to the master system clock.

Movement corrections

The AllSync Plus clock has two primary yet completely separate parts: the circuit board and the movement. The circuit board listens to your master and tells your movement, when asked, the time in its own language. The AllSync

Translator Board will send time to the movement 2.5 minutes after every hourly and 12 hour correction.

Note: The AllSync Plus clock(s) starts its internal clock at 12:50 when power has been removed from it by more than about 25 minutes.

Start Up Example Operation:

Note: This is an example of how the AllSync Plus clock will operate with an ATS master running clock code 01 and actual (master) plug in time at 9 am.

Appendix A - LED Indication

AllSync Plus Clock Installation & Operation Manual

Note: LED indicator can be found on the back of the AllSync Plus clock on the side of the dust cover as indicated by the decal, or refer to picture on page 16.

Normal Operation:

Flashing Green (0.5 sec. ON – 0.5 sec OFF) = Microprocessor is sending an update to the movement.

Note: Time is sent after every hourly and 12 hour correction.

Alternating Red and Green (0.5 sec Red – 0.5 sec. Green) = AllSync Plus circuit board receiving correction signal from master.

Continuous Red = Power is on and the AllSync Plus circuit board has not received a 12 hour correction in last 15 hours.

Note: If the AllSync Plus clock is installed in a clock system running a correction protocol different than 01 (factory) or its previously recognized protocol, it may require more than one 12 hour correction to adjust its internal clock. In this case the LED will remain red after one 12 hour correction.

Continuous Green = Power is on and the AllSync Plus circuit board has received at least one 12 hour correction in the last 15 hours.

AllSync Plus Clock Installation & Operation Manual

Glossary

Clock Protocol - A specific time and duration of a set of correction pulses sent from a master clock to synchronize a clock system. Through the development of clock systems many different clock system manufacturers designed their own clock protocols. For this reason clocks cannot generally move from one system to another unless the system has the same clock protocol. The AllSync Plus clock is designed to recognize many different clock protocols.

Cold Start - AllSync Plus operational state in which power is applied for the first time or after the clock has not had power for a sufficient amount of time to drain it to the point it resets its internal processor.

LED - Light Emitting Diode - Indicator light on the back of the AllSync Plus clock.

Master Clock - In a clock system, a device that acts as the source of time. The master clock transmits the time to any number of secondary (or slave) clocks.

Movement - The inner mechanism of an analog clock that moves the clock’s hands.

Secondary Clock - Also known as a slave clock, this is a clock that synchronizes its timekeeping to that of a connected master clock.

Synchronization - The process of bringing two clocks or time sources into phase so their difference is zero. In the case of a timekeeping system, time synchronization takes place between the master clock and all secondary clocks.
