Whether in the transport industry or manufacturing industry, timer relays play an important role that ensures every system runs optimally. Timer relays create patterns which operationalise actions. Most importantly, relays allow the automation of industrial processes that would otherwise take a large workforce to run. However, it is crucial to keep the parts in excellent condition for timer relays to function optimally. This article highlights critical timer relay maintenance tips.  

Tight Connections -- Timer relays involve movable contact points. Therefore, for the timer relay to accomplish the intended action, the contact points must be close enough. If the contacts are not tight, then the slightest misalignment prevents the contact from touching and completing the command. Therefore, it is imperative to schedule regular maintenance services with an engineer who has the necessary tools to tighten any loose connections. Usually, lose timer relay connections indicate the presence of vibrations. Therefore, if a timer relay is located in an area that experiences excessive vibrations, you must find a way to dampen the vibrations and inspect the relays for tightness regularly.  

Clean Gaps -- As mentioned earlier, timer relays work by completing electrical commands via contact points. Therefore, the contact points must be free of any dirt or dust for the timers to function optimally. Otherwise, if there are specks of dirt on the surfaces of the contact points, the connections may not be complete. Alternatively, the timer relay might act erratically. During the inspection, first dust the timer relay cover to prevent external dust from getting in. After that, look carefully for the presence of other foreign bodies in every inch of the system. You can use a small maintenance brush to wipe away any dust on the timer relay gasket. If the area is too dusty, you can install a fan to keep the dust from settling on the timer relay.   

Measure Moving Gaps -- When a timer relay is not in operation, there is a gap between the contact points which is referred to as a contact gap. The distance in the contact gaps should, therefore, be measured regularly and compared to previous values. If you notice variations in the measurements, then it could indicate wear, and you might need to replace the contact points. On the other hand, variation in the measurements could also mean loose points which only require tightening. Therefore, you must examine and determine the real cause of the change in the distance of the contact gap. Only then can you decide on the maintenance action to take.
