Program Mode
In the program mode all functions 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 Cycle: sets multiple "ON" and "OFF" times per day for the connected
exhaust/supply fans.
- Wash Cycle: sets multiple "ON" and "OFF" times per day for each zone
independently.
- Wash Duration: sets length of each wash.
- Soak Duration: sets length of each soak.
- Rinse Duration: sets length of each rinse.
- 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 an on-screen
menu which prompts the user to toggle the fans "ON" and "OFF", "Start", "Pause"
or "Stop" each of the five 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 suppression system
microswitch or the thermo switch located in the hood duct collar. If the
fire system discharges or the thermo switch opens 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 five keys.
Manual Fire Mode Switch
In the event of a CPU failure, a toggle switch labeled "Manual Fire Mode Switch"
on the rear board can be turned on to maintain fire protection.
Maintenance & Upgrade
The TAC-3000 is easy to maintain. All relays have built-in indicator lights for status and
diagnosis of problems; relays can easily be removed and replaced as well.
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 TAC-3000 is custom designed and
built for individual applications. However, an additional zone control or
another option can be added by installing a control relay in the
field; there is no need to replace the entire panel.
