Mechanical plant extension timers, also known as “override timers” or “caretaker timers” within the BMS & HVAC industry. Totally mechanically driven by a clockwork spring, therefore no auxiliary supply is required. The moment the setting knob is turned pass zero to the set time required, the output contact switches, the timer will then start running back to zero. When zero is reached the output contact will switch back. If after the initial time has been set, it is required that the set time, or remaining set time needs to be lengthened, shortened or cancelled back to zero, the time setting knob can be turned without harming the mechanical mechanism. The timers benefit from a 16 Amp/250V AC1 changeover contact and is easily fitted to the front of a control panel via screw fixings, which are discretely hidden by the time setting knob. Four time range versions are available 0-15min, 0-60min, 0-6hrs, 0-12hrs.

The FOX.MET range of Mechanical Plant Extension Timers are a replacement for the now obsolete 134 & 136.2 range of timers. The front fitting dimensions being dimensionally the same, that is with a 64mm Dia. front escutcheon label, a centre hole of 8mm Dia. for the centre shaft of the timer and two outer fixing holes 5mm Dia. on a 28.6mm pitch for the fixing holes.

This simple but rugged timer is an ideal override unit for HVAC systems. For example, “caretaker” override to a BMS system in schools, public buildings etc. Also ideal for simple process control applications, including bakery equipment, oven controls and mixing systems.
