Time Delay Relays

TSA141300

Anti-Short Cycle, Solid StateTimer

Description

TheTSA141300 utilizes unique circuitry to provide random start

and lockout delay in one small, rugged, inexpensive package.

When connected as shown, theTSA141300 in a multiple unit

situation, prevents all units from starting at one time with

its random start feature. TheTSA141300 also prevents the

compressor from recycling rapidly which could result in a lock

rotor condition. This lockout delay is initiated at the end of each

operation of the compressor. A momentary loss of power would

also initiate the lockout delay.

Operation

Random Start: With the thermostat closed, when line voltage

is applied to system, a time delay is initiated. At the end of this

delay, the compressor relay will be energized. (Random Start

delay is equal to lockout delay.)

LINE

Anti-Short Cycle: At the end of each cycle, when the

thermostat opens, a lockout delay is initiated which prevents

re-energization of the compressor relay during this period. If

the thermostat is closed after the time delay is completed, the

compressor relay will energize Immediately.

Loss of Power: If there is a momentary loss of power, the

lockout will again be initiated preventing the compressor relay

from energizing for the duration of the delay.
