Selc SET 45-18 Digital Timer for LC Audible Warning Set-up Instructions
PROGRAM BUTTON, FOR SELECTING FUNCTIONS
‘OK’ BUTTON, TO ALTER VALUES
MANUAL OUTPUT OVERRIDE
Important: these style time clocks restrict the output to the yodals when ON, therefore the times need to reflect this, so the ON & OFF times are the opposite to the older mechanical style time clocks.

Press PRG button. “SET” appears with first zero flashing. Keep pressing OK button until you set the first security code digit which is 4. Press PRG button again. Enter second security digit which is 7. Press PRG again. Timer can now be set up or checked. To check what times are inputted without altering; keep pressing PRG which will go through each time for ON & OFF. Dashes (--:--) indicate no time is set and timer will ignore setting, so ALL times must be set. To adjust any times; from step 5, press PRG until hour or minute flashes and use the OK button (keep pressing or hold down) to adjust each time. Set each time (to local instruction, or to standard time which is ON at 2330 and OFF at 0700). Keep pressing the PRG button and set ALL times. Note: the days will all flash at the bottom, however these will not change as the programmed times are the same for all days of the week. These timers are factory set for specific railway use. After each time has been set, press PRG and the following will appear; YEAR > MONTH > DAY > TIME. Use the OK button to set any of these if wrong. Pressing PRG again will show BST/GMT auto change function by either b 1 (ON) or b 0 (OFF). This must be set to b 1 to enable automatic BST/GMT yearly changes. Note: the timer has built in auto leap-year compensation. Press PRG to return to main screen. CHECK the main time is correct; the day is correct and according to the time of the day the ON / OFF icon is showing the correct setting. CHECK all the settings again, especially if any have been changed, paying particular attention to the ON and OFF icon making sure the times are correctly matched.
Pressing PRG and OK buttons together results in the timer being reset and clearing all pre-programmed times and settings, and sets the time and date to 00:00 01/01/12, and BST/GMT setting to b 1 (ON).
If no buttons are pressed, the screen will time out after 30 seconds.
Use the MAN button to change the ON / OFF icon over so the yodals are louder/quieter to test output or to quieten them during engineering work (during the daytime), remember to change back before leaving site if altered.
Battery back-up to keep programmed settings is by a lithium cell and lasts up to five years from date of manufacture. It provides up to 12 months back-up if the mains fail. It is NOT user-changeable, so the timer must be replaced. If exposed to temperatures of +100 degrees celsius, the cell is liable to explosion. If no LED’s lit on buttons, this signifies mains failure. F. M. Spowart v1.0 Nov 2016
