Programmable school clock PCZ-523 F&F
Product description
Programmable timer is used for time control of devices in home or industrial automation systems according to an individual time program set by the user, for example: to switch on school bells or other devices that require short on-off times.
Operation
The timer turns the device on at the programmed time and turns it off after the set time (impulse) in cycles: daily, weekly, working days (Mon÷Pt) or weekend (So, Nd). Pulse length: 1s÷99min59s. The relay has two, independently programmable, switchable program lines controlling alternatively connected receiver (this allows to create, for example, a school bell control program for normal lessons and a separate program for shortened lessons).
Timer functions
AUTOMATIC OPER ATION - operation according to ON-OFF commands programmed by the user in the clock's memory.
MANUAL OPERATION - [ON] permanent contact activation (items 1-5) or [OFF] permanent contact deactivation (items 1-6)
PROGRAM - one of two program lines with individual ON-OFF command entries, controlling the contact switching on the receiver.
ON-OFF COMMAND - a single program entry, according to which the receiver will be switched on and off.
OPERATION CYCLE - a settable, weekly cycle in which the receiver's switching on and off is carried out according to the programmed ON-OFF COMMANDS:
* single day of the week: Mo, Tu, We, Th, Fr, Sa or Su;
* weekdays: Mo, Tu, We, Th, Fr (Monday through Friday);
* weekend days: Sa, Su (Saturday and Sunday);
* daily: Mo, Tu, We, Th, Fr, Sa, Su (Monday through Sunday).
AUTOMATIC TIME CHANGE - The change from winter to daylight saving time is made automatically at night on the last Sunday in March at 2:00 a.m. (by adding 1 hour to the current time). Changing time from daylight saving time to winter time is done automatically at night, on the last Sunday of October at 3.00 am (by subtracting 1 hour from the current time).
DST - Daylight Saving Time - the global name for daylight saving time (free translation: sunlight-saving time). A function that allows you to disable the automatic time change.
DATE LIGHT - In AUTOMATIC OPERATION mode, pressing the OK button displays the set date (dd-mm-yy). After 5sec, the clock will automatically go to the main level.
RESTART - Restart the processor with a special button - necessary if the clock operation function is suspended. It does not erase DATE and TIME settings and CONFIGURATION entries in memory.
MEMORY RESET ("deep" reset) - erases all previous DATE, TIME settings and all ON-TIME commands from memory.
