ABSTRACT OF THE DISCLOSURE An adjustable timing circuit for monitoring intervals between operating periods of a cyclic fluid liquid dis- pensing apparatus is disclosed. The cyclic fluid dispensing apparatus is designed to dispense an excess amount of fluid into a fluid system at periodic intervals. If the fluid system and fluid dispensing apparatus are operating properly, the pressure in the fluid system increases to a predeter- mined level shortly after the initiation of a fluid dispens- ing operation. The adjustable timing circuit monitors this condition and generates an alarm signal if the predetermined level of fluid pressure is not reached within a preset time period which is slightly greater than the periodic interval during which the dispensing apparatus is designed to oper- ate.
