Macromatic RT series Reset Timers are electronic and microprocessor based. This design approach offers highly reliable, repeatable and accurate timing cycles. The RT series is available with or without memory. For applications that require memory, the standard RT Series retains timing cycle status when power is lost. When power is restored the timer continues timing without resetting the timing cycle. For applications that do not require memory, Macromatic offers the product without memory as well. The non-memory version resets the timing cycle to zero when power is removed. When power is reapplied, the timing cycle always starts at the beginning.

Voltage band relays monitor for over and under voltage conditions simultaneously energizing the output relay only when the voltage is within the proper “band” or range of voltage set using the adjustment dials on the relay. Contrast this to voltage “over/under” relays that simply energize the relay output when voltage is above the dial setting threshold.
Voltage Monitor Relays monitor either AC single phase (50-60Hz) or DC voltages to protect equipment for undervoltage and overvoltage fault conditions. The relays can be used as either overvoltage or undervoltage relays, depending on the output contact used. Overvoltage models provide protection to equipment that cannot handle excess voltages. Undervoltage relays provide protection to equipment that is required to operate above a certain minimum voltage. Voltage Band Relays provide protection to equipment that is required to operate within an upper and lower voltage limit. As long as the operating voltage remains within an OVER & UNDER voltage range, the internal relay stays energized. If the operating voltage falls outside this range, the relay will drop-out.
Macromatic relays specify the power consumed by the device as “burden” in units of VA. Look for the burden specification in the catalog page for the specific device you have. The unit of VA(volt-amps) is essentially the same as Watts(power), current draw can be calculated in Amps by taking the VA specification and dividing by the voltage control voltage you are using to power the device.

If you need to set the ON and OFF time independently on a cycle timer then you need to select a product with either Repeat Cycle ON or repeat cycle OFF function. Although the operation is similar, Flasher ON and Flasher OFF function do not allow for independent setting of the ON and OFF times.
This is an OFF Delay function. This function is available in several of our time delay relay product lines. Select the time delay relay series that works best for your application.
Product specifications for all Macromatic time delay relays state a minimum of 50 ms in length for the application of a trigger.

Yes, the PMP and PMD Series offer a user-adjustable delay of 0.3 – 30 seconds trip delay for Unbalance, Overvoltage, and Undervoltage faults. Remaining Macromatic three phase monitor relays have factory set time delays built in to minimize nuisance trips while offering best in class protection.
A phase reversal condition would cause rotating equipment to run backwards. Most often this condition occurs due to miswiring during service. All Macromatic three phase monitor relays include protection from phase reversal allowing you to prevent running of the equipment under this condition.

First consult pump documentation as some pumps have specific requirements. If none, dial the sensitivity to its highest level(highest resistance). If the relay gives no alarm you are done. If you receive a seal alarm, adjust the sensitivity back down until the alarm clears. Typical seal leak detection applications use sensitivity settings from 5K to 50K ohms. Lower values are less prone to nuisance alarms but are also less sensitive to the onset of seal leakage.

A Percentage Timer is a time delay relay commonly used in applications such as irrigation, chemical feeding, electric heating & cooling, motors and lubrication systems. Early Percentage Timer designs were mechanical and used motors and gears to perform the timing function. The mechanical nature of these early designs also means that they are susceptible to variations in voltage and frequency. Macromatic PTA series Percentage Timers are electronic and microprocessor based. This design approach offers highly reliable, repeatable and accurate timing cycles. Changing voltage and frequency does not impact the time range or timing cycle.
