ERT/ERTC-01
is a microcontroller controlled programmable time relay device with a
wide range of time scale designed to operate in one of 4 different functions that are
On delay
,
Off delay
,
Down timer
,
Flasher
modes. Output relay is controlled by set
value that can be set between 1.0 sec 100 hours. Programmed function and set
values are recorded at non-volatile memory. Functions and set values can be
programmed easily by buttons on the front panel. ERT/ERTC-01 has optically isolated
Start, Stop and Reset inputs.
Functions:
On Delay:
In the On Delay mode, after the device is energized, the timer starts to
count up and when it reaches the adjusted time , the relay is energized.
(dLYOn)
Off Delay:
In the Off Delay mode, after the device is energized and with start input ,
the relay is energized and becomes de-energized at the end of the time adjusted by
the user.
(dLYOFF)
Down Timer:
In the Down Timer mode, after the device is energized, the down counter
starts to count down from the time adjusted by the user and when it reaches zero, the
relay is energized.
(dO Cnt)
Flasher:
In the Flasher mode, after the device is energized, when
tOFF
time ends the
relay is energized and becomes de-energized at the end of the
tOn
delay
(FLSHEr).
The
starting mode of the flasher mode can be choosen with
StOFF
or
StOn
. In the StOFF
mode flasher starts with tOFF and energized after the tOFF value, then continiues to
tOn mode. In the StOn mode flasher starts with tOn and deenergized after the tOn
value, then continues to tOFF mode. The Flasher function is continuously repetitive.
Inputs:
Start input is used to begin counting, Stop input is used to end counting and
Reset input is used to clear counter in dlYOn,dlyOFF and FLSHEr. In dO Cnt mode
reset, sets the dO Cnt value. One of this three inputs activated by connecting them
to GND.
Function Select:
The device is programmed by pressing the SET buttun for 3 secs. Then program menu
starts with blinking of dLYOn. With UP and DOWN button desired mode dLYOn,
dLYOFF, dO Cnt or FLSHEr, and the mod led blinks. After pressing the SET button
display stops blinking that this mode is choosen. Pressing once to SET button shows
the old time value of this mode with blinking and this could be adjusted with UP and
DOWN button. Pressing to UP or DOWN button continious, increases or decreases
the left digit. For all the other functions, the left digit is changed the same way. After
adjusting the time value, pressing the SET button stops the display blinking, but led
button still blinks (Note that this setting operations need a few steps more for FLSHEr
mode). After pressing the SET button last time mod led stops blinking, desired mod
and value are set and writed to non-volatile memory.
Device can be started to counting with start input. With stop input device stops
counting until stop input is deactivated. Reset input resets the time values. Device
can be started with pressing set and up button at same time (same function with
start input). Pressing set and down button at the same time stops counting.( same
function with stop input). Pressing DOWN and UP button at the same time resets
counting (same function with RESET input).
