Eurotherm 808 инструкция на русском

808P FOUR SEGMENT PROGRAMMER - USER GUIDE
1.
The 808P has three operating modes:-
IdLE mode - in which it behaves as an ordinary controller. Alter the setpoint (desired temperature) simply by using the Up
and Down buttons.
run mode - in which it is running a time/temperature program of up to four segments (2 ramps and 2 dwells).
HoLd mode - which is a temporary pause in the execution of the program. This can be engaged manually, or automatically
by the holdback facility if the furnace deviates too far from program.
2.
The 808P normally displays both the actual temperature measured inside the furnace and the present setpoint or
desired temperature. This setpoint is held constant in IdLE and HoLd modes, but varies according to the program in
run mode.
3.
Press the PARameter button. On the left of the lower display a letter C or F confirms the units of temperature. The
right hand side of the display will be blank if the 808P is in IdLE, or will show which program segment is in use (r1,
d1, r2 or d2) if it is in run or HoLd mode.
4.
Press the parameter button again to display the program status Prog (IdLE, run or HoLd). You may change this using
the Up or Down buttons. Select IdLE to allow program adjustment.
5.
Press the parameter button again to display the IdLE mode setpoint SP. Press Up or Down to change this value. Note
that this parameter is part of the normal display during IdLE mode, and can be altered then or now with the same
effect.
6.
Lc (loop count) is the next parameter to be displayed. Raise or lower this value to set the number of repetitions of
your program. Note that if L2 is higher than L1 (see below), then at the end of d2 the program will ramp down to L1
at rate r1 as the first stage in the next execution of the program.
7.
r1 represents the rate of change of temperature in °/minute for ramp 1.
8.
L1 represents the first temperature Level that you wish to ramp towards.
9.
d1 is the length of time in minutes that you wish the furnace to maintain the L1 temperature (the dwell at level 1).
10.
r2, L2 and d2 have similar functions for the second set of segments.
11.
Hb allows you to make the programmer pause (Holdback) and to wait for the furnace to catch up with the program, if
the temperature deviates from the program by more the set amount. Hb should be set to about 10° to ensure that dwell
times are not begun until the furnace has reached the programmed temperature level. Hb is factory set to 2000°, and
will have no effect unless reduced to a lower value.
12.
Run your programme by using the parameter button to display the Prog parameter, and use the Up button to select
run. The "R" LED will glow.
13.
Pause the program by selecting HoLd mode. The "R" LED will flash.
14.
Cancelthe program by selecting the IdLE mode. The "R" LED goes off.
15.
After a power failure the program will resume where it left off and complete any remaining part of the current
program segment. Holdback will be automatically engaged if the furnace has cooled by more than the Hb setting.
