Alarm 1 with relay in closed- circuit current mode for pre- liminary warning, releases at over-temperature at PTC-set 1 and serves at the same time as functional monitoring. Alarm 2 in operating current mode. Thus no wiping signal occurs when switching on the supply voltage on. Additional terminals enable comfortable wiring from supply voltage to relays K1 and/or K2.
