A UV Lockout is when the UV System does not allow ignition of the UV Lamps. This can be during a warm up cycle, a cooldown cycle, or any other time the UV System deems unsafe to ignite the lamps. A UV Lockout on a MetalBox system is caused by the Lockout Relay (R1/R2) which is switched on when the Current Relays (CR1/CR2) do not detect any current draw after a lamp is ignited.
