ETAC-3000
PIPING SCHEMATIC
The ETAC-3000 is a solid state,
state-of-the-art control panel which provides the ultimate controlled
internal cleaning system for the water wash ventilation hoods. User
friendly programming via the four line, liquid crystal display allows
the operator to program on and off times for supply and exhaust fans,
create up to 5 wash zones, and to select fan operation during a fire
condition. Optional programming features provide control of the shunt
trip breaker, the building alarm system and the electric gas valve. Door
mounted indicator lights show the status of supply and exhaust fans,
fire condition, water valve and AC power.
The TAC-3000 is equipped with
three modes of operation: PROGRAM, AUTOMATIC and MANUAL. A key switch is
used to select the mode of operation and denies access to unauthorized
users. The key pad is touch sensitive, providing exceptional durability
and longevity. It consists of five keys, up and down arrows; a tab
arrow, select and prior menu. When a key is selected, a tone is
generated to provide feedback while programming.
FEATURES
PROGRAMMING
FEATURES:
- User friendly, menu driven
programming.
- Memory held by internal RAM
battery, so in case of extended power outage or external battery
failure, memory is held indefinitely.
- Program key switch prevents
non-authorized users changing the program.
- Manual mode is able to
override programming and toggle fans, wash zones, and auxiliary
outputs "ON" and "OFF" on demand.
- User selected fan control in
a fire condition, exhaust fan on, both fans on, or both fans off.
OPERATING
FEATURES:
- Capable of controlling 24
hour 7 day program of up to 5 wash zones independent of each other
with user programmable wash, soak, and rinse duration's, and delay
times between each wash.
- 24 hour 7 day programmable
fan control, capable of multiple "ON" and "OFF"
times.
- A programmable Holiday
schedule which turns off the program for the user programmed
holiday. Up to 12 holidays can be programmed.
- Audible alarm, indicating
light, and displayed message for fire indication.
- Shunt trip breaker output.
- A building fire panel
contact for building alarm systems.
HARDWARE
FEATURES:
- Plug in solid state relays
with output indication lights.
- On-board Circuit Breakers
instead of fuses.
- Liquid Crystal Display.
- PIEZO Electronic key pad, no
moving parts to fail.
- Plug-in connectors.
- Indicating lights on front
panel to indicate fire, exhaust and supply fan, zone water valves,
and power outage.
- Manual override switches to
control the fans if CPU fails.
- Maintenance switch to
prevent fire signal tripping when maintenance is being performed.
- A manual lighted push button
mounted on the front door used to send the panel into a fire
condition if needed.
OPERATING MODES
PROGRAM
MODE:
In the program mode all
function can be programmed by the operator. The program menu consists of
the following control lines:
- Set date and time: allows
the operator to change the date and time
- Fan cycles: sets multiple on
and off times per day for the connected exhaust/supply fans.
- Wash cycles: sets multiple
on and off times per day for each zone independently.
- Wash duration: sets the
length of each wash from 1 to 14 minutes.
- Soak duration: sets the
length of each soak from 1 to 14 minutes.
- Rinse duration: sets the
length of each rinse from 1 to 14 minutes.
- AUX 1: sets multiple on and
off times per day for user defined item.
- AUX 2: sets multiple on and
off times per day for user defined item.
- AUX 3: sets multiple on and
off times per day for user defined item.
- Fire condition: operator
selects which fans are ON or OFF in a fire condition.
- Holiday: operator specifies
up to 12 holidays during which the system will not run the
programmed schedule.
AUTOMATIC MODE:
In Automatic mode the system
runs the programming and the screen displays the date, time, and status
of the system.
MANUAL MODE:
Manual mode is used to override
programming and give the operator immediate control of the system. The
operator controls the system through the on-screen menu which prompts
the user to toggle the fans ON and OFF, Start, Pause or Stop each of the
5 wash zones, and toggle the Auxiliary outputs ON and OFF.
BATTERY
BACK-UP:
The system is battery backed up
to prevent false alarms. The program is backed up with an internal
battery which will hold the program indefinitely upon loss of AC and DC
power.
FIRE CONDITION:
The fire trip signal is
triggered through the fire protection system switch or the thermoswitch
located in the hood duct collar or the door mounted manual fire button.
If the fire system discharges or the thermoswitch opens or the manual
fire button is pressed, the TAC-3000 will be sent into a fire condition,
a red fire light will illuminate on the front panel, the panel mounted
alarm will sound, and the display will indicate FIRE. The TAC-3000 will
set the fans to the programmed state, open water valves for all zones,
trip the shunt trip breaker, shut off the gas valve, and signal the
building alarm system. Once the signal is restored, the TAC-3000 is
reset by pressing any one of the 5 keys.
MANUAL FIRE
MODE SWITCH:
In the event of CPU failure, a
toggle switch labeled "Manual Fire Mode Switch" on the rear
board can be selected to "ON" to arm the manual fan switch and
set the fire condition so that in the event of fire, the exhaust fans
will be ON, supply fans will be OFF and the water valves will be OPEN.
The manual "Fans On" switch is used to turn the fans ON and
OFF. This switch is used until a CPU board replacement is obtained.
MAINTENANCE AND
UPGRADE:
The ETAC-3000 is easy to
maintain. In the unlikely event that a relay must be replaced, it can
easily be removed and replaced. Likewise, both circuit boards are
equipped with quick disconnect plugs for easy removal and replacement-
simply unplug the faulty board and plug in the new board. Each ETAC-3000
is custom designed and built for individual applications. However, an
additional zone control or an option can be added by simply installing a
control relay in the field. There is no need to replace the panel- it is
easy to upgrade. In addition all relays have built-in indicator lights
for status and diagnosis of problems.
