[5] = Schedule Changes
Use Schedule Changes to run schedules at a certain date and time. This function works much
like the Bell Schedule Function [4]. Enter your password, then press [#][5][#]. You can
program up to 16 changes at a time
[6] = Enable or Disable Circuits
This function requires the administrator password
Use this function to Enable and Disable bell relays during circuit wiring or maintenance. This
function can also ‘hold back’ clocks to manually adjust for daylight savings in the fall if you
do not use the Daylight Savings function [7]
Disabled relays will ignore any schedules, and you cannot manually turn them on
([3]=MANUAL BELL CTRL). After you complete and check your system wiring, use this
function to enable those circuits, so that they will turn on when called. Enter your password,
then press [#][6][#]
[7] = Daylight Savings Time
This function requires the administrator password
Your LTRx-512 knows the daylight savings time (DST) settings for over 75 countries. By using
the 2-digit “country code”, your LTRx-512 will automatically adjust for daylight savings time. If
your nation does not appear in the Country Code list, you can choose code ‘00’ and use
Lathem’s LTR MasterLink software to program when clock adjustments should occur
Enter your password, then press [#][7][#]
Enter your country code from the list in Appendix C or press [9] to see the list. Press [9] to
jump to each letter in the alphabet, then press [#] to scroll through the codes. (example: press
[9] to jump to 08: BAHAMAS, BERMUDA, press [9] again to jump to 08: CANADA, press
[9] again to jump to 02: DENMARK and so on). When you see your country code, enter it,
then press [#]
If your region does not observe daylight savings, then leave the country code at 00
[8] = Change Schedule
Use this function to override any active bell schedules that you setup in function
[5]=SCHEDULE CHANGES. Or, you can use this function to instantly run a schedule that you
