Wash Cycle Notification and Monitoring
Overview
The Wash Cycles for the Ventilator Extractor, Ventilator Plenum, Pollution Control Unit (PCU), and Duct Sump are programmed to come on based on the Cooking Equipment Duty. The programmed Cooking Equipment Duty dictates the number of hours of fan operation before the Wash Cycle comes on. Refer to Table T-3-1-1, Typical Example of Frequency and Length of Wash Cycles, on Page 3-1 for typical application. Washing the Ventilator based on hours of operation for specific Cooking Equipment Duties provides the optimum in cleaning performance with the lowest possible water and detergent consumption.
Screen Display When in a Wash Cycle – ELXC Series Ventilator
The ELXC Ventilator has two Wash Cycles, the Plenum Wash and the Extractor Wash. The Plenum Wash only comes on when the exhaust fan is off and the Extractor Wash only comes on when the exhaust fan is on. A Wash Cycle sequence is as follows:
Plenum Wash
1.While the exhaust fan is off, and when the hours of fan operation have been satisfied, as programmed by the Cooking Equipment Duty, the Plenum Wash will start and the display as shown on Figure 2-7-1 will come up.
2.The countdown clock shows the number of seconds left before the Wash Cycle turns off. The example in Figure 2-7-1 shows that Plenum Wash 1 is on and that there are 14 seconds left in the Wash Cycle.
3.Upon completion of the Plenum Wash, and if there are no additional Plenum Washes (Plenum 2, 3, 4 etc) then the display as shown in Figure 2-7-2 will come up.
Figure 2-7-1 Figure 2-7-2
Important Note: The Plenum Wash may be stopped at any time by bushing the STOP WASH(S) as shown in Figure 2-7-1.

PCU (Pollution Control Unit) Monitoring
If the Ventilator includes a Pollution Control System, Gaylord SPC Series (Smoke Pollution Control) or if there is a PCU (Pollution Control Unit) Gaylord Model RSPC-ESP Series, remote from the Ventilator, the Command Center monitors the status of two basic functions 1) The status of the ESP Cell and Power Pack (Electro Static Precipitator), and 2) if the system uses chemical to control the odor, the system notifies of a Low Oder Control Chemical condition. To check the status, proceed as follows:
1.While the exhaust fan is on, at the bottom of the display as shown in Figure 2-14-1, the button in the center reads CHKSYS which stands for Check System. When this button is pushed, and if the system is operating properly, the display as shown in Figure 2-14-2 will come up. If there is a problem the display as shown in Figure 2-14-3 will come up.

1.To check the detailed status, push the ESP CHECK STATUS button, as shown in Figure 2-14-3, and the display as shown in Figure 2-15-1 will come up if the system is operational or Figure 2-15-2 if there is a problem with the Cells or Power Pack. The “A” and the “B” squares indicate that there are two ESP Power Packs. Each Power Pack can serve up to 4 ESP Cells, so if there were 8 Cells there would be two lettered squares, as shown in Figures 2-15-1 and 2-15-2, 12 cells three lettered squares, and 16 Cells four lettered squares. If there are no problems with a Power Pack or associated Cells, the lettered squares will have a dark background as shown in Figure 2-15-1 and the text at the bottom will read ESP OK. If there is a problem with the ESP Cells or Power Pack(s), the display as shown in Figure 2-15-2 will come up and the text at the bottom will read ESP FAULT. In this example, the “A” Power Pack is operating properly and the “B” Power Pack has a problem.
2.If Spray Odor Control is used, and if the there is chemical in the tank, the display will include the text LOW ODOR CHEM OK as shown in Figures 2-15-2 and 2-15-2. If the chemical tank is empty, the display will include the text LOW ODOR CHEM LOW as shown in Figure 2-15-3.
Important Note: The recommended spray odor control chemical is Gaylord Formula GS-710 and is available from the same Gaylord Distributor that provides Formula G-510LF used for the Ventilator Wash system. See page 2-19 for ordering information.

Fire Extinguishing System Monitoring (External Fire Mode)
If a Ventilator includes a Fire Extinguishing System, the Command Center interacts with the fire system and various building systems. This is referred to as an External Fire Mode. If the Fire Extinguishing System discharges, the Command Center reacts as follows:
1.The display as shown on Figure 2-16-1 comes up. This display will stay on until the fire system is reset.
2.The protected cooking equipment and possibly other cooking equipment will shut off.
3.If the Fire Extinguishing System is wired to a building fire alarm system the alarm will activate.
4.If the Fire Extinguishing System is wired to a building management system (BMS) it will notify of a fire condition.
5.If the Fire Extinguishing System is wired to the Gaylord Command Center the following will occur:
a)If the exhaust and supply fan were on the exhaust fan would stay on and the supply fan would shut off. It the exhaust and supply fans were off, the exhaust fan would come on and the supply fan would stay off.
b)If the Ventilator Wash Cycle was on it would shut off.
c)If the Ventilator is equipped with a Gaylord Electric Balancing Damper (model GEBD) or a Gaylord Fire/Balancing Damper (model GFBD) the damper will open.
d)If the Ventilator is equipped with UV Lamps the Lamps will shut off.
6.After discharge, the Fire Extinguishing System must be recharged and once recharged the display as shown on Figure 2-16-2 will come up. The exhaust fan can now be started and the cooking equipment can be turned back on.
