(Alternating Relay)

Timer Functions

Counting and Switching Functions

OPERATION: Input voltage must be applied before and during operation. The operation begins with

the output (relay or solid state) de-energized. Upon momentary or maintained closure (leading edge

triggered) of the initiate switch S1, the time delay begins. At the end of the time delay, the output

energizes and remains energized. Opening or re-closing S1 during timing has no affect. After the output

transfers, the next closure of S1 starts a new operation. Each time an S1 closure is recognized, the time

delay occurs and then the output transfers, ON to OFF, OFF to ON, ON to OFF. The rst operation will

occur if S1 is closed when input voltage is applied.

RESET: Removing input voltage resets the time delay and the output to the de-energized state.

Function can be applied to ProgramaCube Series: HRPS, KRPS, KSPS

OPERATION: Input voltage must be applied at all times for proper operation. The operation begins

with the output (relay or solid state) de-energized. Closing S1 enables the next alternating operation.

When S1 opens (trailing edge triggered), the time delay begins. At the end of the time delay, the output

energizes and remains energized until S1 is (re-closed and) re-opened. Then the output relay de-energizes

and remains until S1 opens again. Each time S1 opens the time delay occurs and the output transfers.

RESET: Removing input voltage resets the output and the time delay.

Function C)

Counter with Interval Output: (ProgramaCube

Function CI)

Function Limited to Switch Adjustable ProgramaCubes

OPERATION: Input voltage must be applied before and during operation. Each time S1 is closed, a count

is added. When the total number of S1 closures equals the total count selected on the unit, the output

energizes. The output remains energized for the pulse duration specied for the product, and then de-

energizes. If S1 is closed while the output is energized, a count is not added. If S1 is closed when input

voltage is applied, a count is not added.

RESET: The unit automatically resets at the end of each operation. Removing input voltage resets the

output, counter, and pulse delay.

Function Limited to Switch Adjustable ProgramaCubes

OPERATION: Input voltage must be applied before and during operation. Each time S1 is closed, a count

is added. When the total number of S1 closures equals the total count selected on the unit, the output

energizes and the interval time delay begins. The output de-energizes at the end of the time delay. If

S1 is closed during the time delay, a count is not added. If S1 is closed when input voltage is applied,

a count is not added.

RESET: The counter is reset during the time delay, the unit automatically resets at the end of the interval

time delay. Removing input voltage resets the output, counter, and time delay.
