... MSC2). NEVER install suppressors directly across the output contacts of ! the ES-FL-2A safety relay possible for suppressors to fail as a short circuit. If installed directly across the output contacts of the safety relay, a short-circuited suppressor will create an unsafe condition which could result in serious injury or death ...

... The action of the auxiliary monitor contact, K3, inversely “follows” the action of the output relays, K1 and K2 when power is applied to the ES-FL-2A safety relay. The contact open when the output contacts of K1 and K2 are closed, and vice versa. The K3 auxiliary monitor contact is a light-duty contact to be used only for control functions that are NOT safety-related. A typical use is to communicate the status of the safety relay output to a programmable logic controller (PLC) ...
