This gfci breaker is an expensive item but vital to making the whole brewery safe.
Wiring temperature control panel.
Second how high or low of a temperature can the interior components withstand and will thermal devices need to be added to remove or add heat.
The panel and all penetrations must maintain the proper nema rating.
Wiring the temperature panel when the electric lock is a strike the relay in the biometric panel can be programmed to close only if a person s temperature is normal and wearing a mask.
You can select temperature scanning mask detection or both conditions for entry control.
The very popular tri rated cable rated under bs 6231 is a kind of high temperature fire retardant cable specifically designed for control.
These are some general points that should be taken into account when wiring the control panel.
Terminal blocks secure wires to the controller.
Conductor and cable runs.
We get many questions about the basics of electrical control panels such as what devices and equipment we typically use how the devices are wired how to keep the control panel and the cabinet within a normal temperature range and so on.
To field wire connect low voltage wiring from the hood sensor terminals located in a junction box on end of hood to sensor terminals s1 s2 located in control panel.
For a system controlling more than one hood connect hood sensor 2 to s3 s4 hood sensor 3 to s5 s6 and hood sensor 4 to s7 s8.
More accurately the pictured setup uses a 240vac 30a gfci breaker installed at the service panel to make the 4 wire dryer outlet that the control panel dryer cord plugs into gfci safe.
Conductors of different circuits.
Connections should be secured against accidental.
In addition to the obvious need to be able to turn the temperature control panel off an on the manual off switch is an important safety feature.
Control wiring can be any of the wiring methods allowed for power circuits within the panel with the addition of power limited circuit cable such as type pltc cl2 or cl3 and communication cable such as types cm cmr or cmp.
2 control circuits are unique in that many controls now use industrial networking cabling technology.
Control panel wiring colour codes per en 60204 1.
They also reduce wiring by having a common connection point for power supply and communications interfaces.
They are a necessity for external control devices as they allow the digital.
This is especially critical for outdoor industrial control panel and those with sun exposure.
