Time Delay Relays
Issue: How do I convert from an obsolete SS-4 product with a spade base socket to one with an octal base socket? Solution/Resolution: The Macromatic SS-4 spade base products were obsoleted on August 1, 2010. If you have an application that uses an SS-4 product and need a replacement, you have two options: (a) switch
Issue: I am using a time delay relay with a triggered function. My trigger switch will be closed before I apply voltage to the time delay relay. Will this work? Solution/Resolution: In a typical application with a triggered time delay relay, voltage is first applied to the timer, then the trigger is applied to begin the function. Some applications, however, require the trigger to be closed before voltage is applied. Most Macromatic time delay relays will recognize the trigger when applied prior to the application of voltage, however, some will not.
Issue: The output relay appears to be already energized on my True Off Delay timer without any input voltage applied. It was that way when I received it or I found it in that state during installation. What happened and how do I fix it?
The Macromatic TR-6 Series Time Ranger programmable time delay relays have gone through an extensive redesign that was introduced in February 2017.
Issue #1: I have the control switches from 5 separate OFF Delay time delay relays from other manufacturers wired in parallel so one switch can operate all 5 at once. However, when I replaced one of the original units with yours, the Macromatic product operated once and then stopped working. What’s wrong?
Differences Between the Obsolete SS-5 & SS-6 Series Time Delay Relays vs. Current TR-5 & TR-6 SeriesMonday: February 13, 2017
The SS-5 Series and SS-6 Series of plug-in time delay relays were manufactured by Macromatic through the summer of 1999. At that time, they were replaced by the TR-5 & TR-6 Series, the next generation of Macromatic plug-in time delay relays. The TR-5 Series was further updated in 2012 and a redesigned TR-6 Series was introduced in 2017 with major changes.
The THS-1054A series offers accurate and reliable operation as a Low Pressure Switch Bypass or “Bypass Timer”. The time delay relay operates over a wide temperature range making it a good choice for winterstart applications having low ambient startup temperatures.
Issue: How do I set the THL-8 Series Time Delay Relay?
Solution: All THL-8 Series products come with a specific single time delay range as indicated on the nameplate and by the two-digit code at the end of the Product Number. Setting the time delay is accomplished through the use of a 10-position DIP-switch.
Issue: I am using a TR-61626 Programmable Time Delay Relay with a special pin configuration with the trigger switch between pins 7 and 10 that needs to be replaced but now I am told it is no longer available. What can I do?
Modification to Order a Product that is Normally an 8 Pin Product with 11 Pins (-H Suffix) No Longer AvailableTuesday: December 1, 2015
Issue: In the past I have purchased a time delay relay with the H option, but it is now obsolete. What can I do? Solution/Resolution: We certainly apologize that this option is no longer available and therefore, may cause some inconvenience for you. This option was to take a time delay relay that normally came
