Wiring the Master Clock This section provides instructions on wiring the power source, secondary clocks, and sig - naling devices to the master clock. It does not cover the connection of the optional modem, a computer, any RS-485 devices, and a power source for the optional remove schedule selector.
1. Wire the power source to P4 as shown in either Figure C-1 or C-2 on page C-2. Note: The master clock is shipped set up for 120Vac operation. To wire it for 220/240Vac, change the jumper settings as shown in Figure C-2 .
2. Wire the secondary clocks to P1 and/or to P2. See Wiring Secondary Clocks on page B-2 for complete instructions. Note: You may need to add external metal-oxide varistors (MOVs) or diodes to synchronize a specific clock type. See the clock wiring diagrams in Appendix B .
Setting Up the Master Clock Once the master clock is installed, it is ready for programming. This chapter covers the programming instructions needed to set the master clock for operations.
Programming Functions This section explains how to put the master clock in program mode and configure the necessary functions to get the master clock running. For definitions of all functions, key pad commands, and the bell test, see Section 3—Function List .
Setting the Date and Time Use the [1]=SET DATE / TIME function to set the date and time. Enter the user password as shown on page 2-2, then follow the key sequences below: Press Display [#] SELECT FUNCTION CODE [1] [1]=SET DATE / TIME [#] ENT. DATE: MM-DD-YYYY [0].
Enabling the Relays Use the [6]=ENABLE CIRCUITS function to enable or disable the master clock’s con - trol relays during circuit wiring or maintenance. This function can also hold back clocks to manually adjust for daylight saving time in the fall if the daylight saving function is not in use (see Setting Daylight Saving Time on page 2-7).
Choosing the Clock Types to Synchronize To select a clock type for the master clock to synchronize, use the [2]=SELECT CLOCK CTL function. This allows you to match the master clock to the type of secondary clocks installed. This function configures both clock #1 (relays 7 and 8) and clock #2 (relays 5 and 6), if present.
Manually Activating Bell Controls Use the [3]=MANUAL BELL CTRL function to test the bell circuits. This function does not require a password. Follow the key sequences below: Press Display [#] SELECT FUNCTION CODE [3] [3]=MANUAL BELL CTRL [#] MANUAL BELL CONTROLS 1-2-3-4-5-6-7-8 PRESS AND HOLD [#] TO EXECUTE.
Testing the Bells Use the AUTO BELL TEST function to turn on all bell relays once per minute at the start of each minute. This tests the continuity of the bell wiring circuits.
Setting Communications The [B]=COMMUNICATIONS function is used to enter data transmission speed and a terminal ID number. Use this function if the clock will be programmed to call the NIST atomic clock, or if you are using the optional Lathem MasterLink software to program the master clock.
Securing the Setup At this point you have finished the basic setup of the master clock and it should be up and running. The clock can now be programmed with user-specific settings such as bell schedules and holidays. For detailed information, see the Master Clock User Guide, doc - ument 427-07-00047.

Wiring Secondary Clocks The next several pages contain wiring diagrams and theory of operation for the secondary clocks. These are listed in numerical order according to type code number. Note: All circuits should be fused or protected by a circuit breaker (10A maximum).
Please note that the relay contacts used in the CLK2 circuit are rated at 10 amps. The combined load of the correction circuit and the run circuit should not exceed 8 amps. In general, 20–35 analog clocks can be operated on a single string. This number depends on the clock style and the distances involved.
TYPE 02—Three-Wire Minute Impulse (59th Minute) There are two types of Type 02 secondary clocks: the three-wire minute impulse covered on this page, and the two-wire reverse polarity minute impulse on the following page. Note: For a list of Type 02 clocks, see the chart on the first page of this appendix.
TYPE 02—Two-Wire Reverse Polarity Minute Impulse (59th Minute) There are two kinds of Type 02 secondary clocks: the two-wire reverse polarity minute im - pulse covered on this page, and the three-wire minute impulse on the previous page. Note: For a list of Type 02 clocks, see the chart on the first page of this appendix.
TYPE 03—Standard Electric Synchronous During normal operation, 120Vac is applied to the run motor. A 15-minute correction signal on the correction motor line causes a 12-hour correction from 5:12:00 to 5:28:00. This occurs twice daily (AM and PM). Run motor power is connected during the 12-hour correction.
TYPE 04—Standard Electric Time AR-2A Two-Wire, Dual Voltage Each minute, from 58 seconds to 00 seconds, a low-voltage pulse (24Vdc) is transmitted. The secondary clocks receive the pulses until the 59th minute. At this time, from 50 sec - onds to 00 seconds, a higher voltage pulse (48Vdc) is required to advance to the hour.
TYPE 05—Three-Wire Minute Impulse (58th Minute) Each minute, from the 58th second to 00 seconds, a 24Vdc pulse is transmitted to the sec - ondary clocks. From the 58th minute through the 48th minute, the pulse is transmitted on both the A and B lines.
TYPE 06—Synchronous Wired For a list of Type 06 clocks, see the chart on the first page of this appendix. The clock run motor receives 120Vac continuously, with 120Vac furnished to the clock correction coil for 55 seconds each hour from HH:58:05 to HH:59:00 to cause hourly corrections.
TYPE 07—Dukane Digital Clocks For a list of Type 07 clocks, see the chart on the first page of this appendix. —IMPORTANT— Dukane digital clocks MUST be connected to CLK1 (relays 7 and 8) on the master clock.

TYPE 09—Simplex 59th Minute, Dual Motor Power is normally applied to the 1 RPM run motor. Each hour, from HH:58:05 through HH:58:59, power is removed from the run motor and applied to the fast advance motor. During manual clock corrections, power is applied to both motors for 4 minutes and 15 seconds.
TYPE 11—Edwards Dual Motor Power is applied only through relay K6 to the run motor for normal timekeeping. During power interruptions (while clocks are stopped) and during correction, the master clock accumulates the number of seconds. Immediately after power is restored, both relays K6 and K5 operate.
TYPE 12—Cincinnati D6 Clocks Normal pulsing is sent out on lines A and C from second 58 through second 00 each minute. From minute 59 through minute 49, line A is positive with respect to line C. From minute 50 through minute 58, except from 4:49 through 5:55 AM and PM, line C is positive with respect to line A.
TYPE 13—Two-Wire Pulse Alternating (24Vdc) Every minute from 59 seconds to 00 seconds, a 24Vdc signal is applied on lines A and B, causing the clocks to advance one minute. The polarity of the pulse is alternated each minute to cause A to be positive with respect to B one minute, then B positive with re - spect to A the next minute, and so on.
TYPE 14—Electronic Coded Clocks Clocks normally run with 120Vac power. For bells or clock correction, the generator prestart relay (K6) first turns on for the signal generator to reach frequency. K6 turns on at the 00 second after a programmed time or manual bell time.

TYPE 15—Straight Frequency Clock correction and bell circuit operations are generated by sequentially applying vari - ous frequencies onto the 120Vac. Each bell and clock correction circuit has its own frequency and a receiver circuit that applies the associated bell or clock frequency (3,510Hz normally used for clock signals).
TYPE 16—Three-Wire Minute Impulse (59th Minute) with 12-Hour Correction There are two types of type 16 secondary clocks: the three-wire minute impulse covered on this page, and the two-wire reverse polarity minute impulse on the following page.
TYPE 16—Two-Wire Reverse Polarity Minute Impulse (59th Minute) with 12-Hour Correction There are two types of type 16 secondary clocks: the two-wire reverse polarity minute impulse covered on this page, and the three-wire minute impulse on the previous page.
TYPE 17—Standard Electric Time AR-3 Three-Wire Impulse Each minute from 58 seconds to 00 seconds, a pulse is transmitted on line. The secondary clocks receive the pulses on line A until the 58th minute. At this time, from 50 seconds to 00 seconds, a pulse on line B is required to advance to the 59th minute.
TYPE 18—National Synchronous Wired For a list of Type 18 clocks, see the chart on the first page of this appendix. Relay K5 is normally operated to power the clock run motors. Each hour from HH:00:00 to HH:00:28, relay K6 is operated to power the clock correction coils for 28 seconds and cause hourly corrections.
TYPE 19—Stromberg Synchronous Wired (56th Minute) For a list of Type 19 clocks, see the chart on the first page of this appendix. This clock is normally operated by 120Vac/24Vac.
TYPE 20—Three-Wire Minute Impulse (44th Minute) Every minute, from the 58th second to 00 seconds, a 24Vdc pulse is transmitted to the secondary clocks. From the 44th minute through the 34th minute, the pulse is transmitted on the A and B lines. From the 35th minute to the 44th minute, the pulse is transmitted on the A line only.
TYPE 21—Cincinnati D1 Every minute, from HH:MM:58 to HH:MM:00, relay K6 is activated, causing an output on line A for two seconds. During minutes 07 through 58 only relay K6 activates, causing the output on line A to be 24Vdc.
TYPE 22—Dukane Synchronous Wired (24A Series, Obsolete) During normal operation, either 24Vac or 120Vac is furnished to the clock run motor through relay K6. Power is removed from the run motor during power failures, while K6 de-energizes during fall daylight saving changes.
TYPE 23—Condor Digital Clocks (Model 2412) For a list of Type 23 clocks, see the chart on the first page of this appendix. Condor digital clocks initialize to 12:00 AM when power is first applied. During normal operations, the clocks maintain time by counting the 60Hz AC line frequency.
TYPE 24—Edwards Synchronous Wired Clocks, Type E1 During normal operation, 120Vac is applied between the run motor and common lines to operate the clocks until the 58th minute. At HH:58:00 of each hour, the 120Vac is re - placed by 120Vdc between the correction and common lines for a period of 200ms, with the common line being positive.
TYPE 27—Simplex 2310 Dual Motor Type 27 secondary clocks have the same hourly corrections as type 09, with the addition of 12-hour corrections as for type 03. Power is normally applied to the 1 RPM run motor. Each hour, from HH:58:05 through HH:58:59, power is removed from the run motor and applied to the fast advance motor.
