Abstract

PURPOSE: To prevent setpoints from changing in case setting means is operated unexpectedly by composing a control circuit in digital circuit and storing alarm level points temporarily in a memory unit by setting means to set.
CONSTITUTION: The detected input signal S is introduced into a central processing unit 23 from a contact 24A of a changeover circuit 24 via an A/D converter 25, whle an alarm level point signal, set by a setting means 26, is introduced into the central processing unit 23 from a contact 24B of the changeover circuit 24 via the A/D converter 25. When an alarm setpoint indication switch 31 and a designation means 29 are manipulated, the processing unit 23 delivers a control signal to the changeover circuit 24 to close the contact 24B, and introduces and stores the alarm level point information which is set by the setting means 26 in the region of memory unit 27 designated by the switch 29. When the manipulation of the designation means 29 and the switch 31 is canceled, the processing unit 23 will close the contact 24A of the changeover circuit 24 to perform a detecting action
