Troubleshooting a Unit with a Control Switch Trigger

Saturday: August 29, 2015 : Time Delay Relays

Issue: I am using one of your products that has the control switch trigger between Pins 5 & 6, and the unit is not operating. What could possibly be wrong? Solution/Resolution: Normally when we receive this question, the problem is traced to a blown resistor in the control switch trigger circuit. Most of the time

DC Input Voltages on Time Delay Relays

Saturday: August 29, 2015 : Time Delay Relays

Issue: I have applied 24VDC input voltage to one of your time delay relays, but the product still doesn’t operate. I know the voltage supply is good. Solution/Resolution: Any of our time delay relays that operate on dc are polarity dependent. This means that it is important to connect the “+” & “-” wires to

Definition of Repeat Accuracy

Saturday: August 29, 2015 : Time Delay Relays

Issue: What does "repeat accuracy" mean in the Application Data section of your time delay relays? Solution/Resolution: Repeat accuracy is the percent variance of time within consecutive timing cycles once a time delay relay is set to the required time delay. For example, our TR-6 Series programmable & TR-5 Series non-programmable units have a repeat

Using the 70166 Hold-Down Spring

Thursday: August 20, 2015 : General Articles

Issue: How do you use the 70166 hold-down (tie-down) spring on the Macromatic 70169-D or 70170-D sockets when mounting the socket with two screws on a panel? What about when mounting the sockets on 35mm DIN track? Solution/Resolution: To use when panel-mounting the socket, put one screw through the end of the spring and then

Input Voltage Applied But Nothing Coming Out!!

Wednesday: August 12, 2015 : Time Delay Relays

Issue: When I apply 120V to the input terminals of a time delay relay, why don’t I get 120V out of the output contacts to control my load? Solution/Resolution: Think of a time delay relay as nothing more than a control relay with a time delay built-in. When you apply voltage to a control relay,

Connection of Pump Seal Failure (Seal Leak) Relays in Submersible Pump Applications

Monday: August 10, 2015 : Seal Leakage & Temperature Relays

Issue: I need to know how to install and connect the wiring for my seal leak probe to a Macromatic Seal Failure Relay. Solution/Resolution: Making the right connections: Seal leak probes are typically built into, or attached to, the submersible pump. Most pumps will have only a single seal leak probe, but may have one

Macromatic Products & 50/60Hz Applications

Monday: August 10, 2015 : General Articles

Issue: Will Macromatic products work at 50 Hertz, as required in other parts of the world? Solution/Resolution: Electrical equipment is made by the manufacturer to operate at a specified Current, Voltage, and Frequency (Hertz). The Current is dependent on the Voltage and Hertz. If the Current through the equipment is greater then it is designed
