By: R. L. Worth Jr. , Service Support Coordinator Astec Service Department PURPOSE: The purpose of this letter is provide instructions for replacing an Agastat SSFR90A, universal timing relay, with a Siemens 3RP1505-1BQ30. This conversion should only be performed by qualified individuals. PARTS REQUIRED (for each replacement): Quantity Astec part number Description 1 054734 Siemens Sirius relay, Siemens item # 3RP1505-1BQ30. 1 054735 3RP1901-QB, Label GETTING STARTED: Before un-wiring and removing the Agastat timer, make sure all wires are labeled. Remove the Agastat timer from the DIN rail. Mount the Siemens in it’s place. Use your current electrical schematics to determine the current configuration you have. The terminal numbers on the new Siemens relay are identified differently than those on the Agastat. Refer to the following examples for wiring instructions. After the conversion is made it will be helpful to note the changes on your electrical schematics. The new Siemens relay will perform the same as the Agastat, once it is configured properly. Please refer to the following examples for configuration instructions. EXAMPLES: RELAY FUNCTION EXAMPLE # PAGE #ON DELAY #1 2 OFF DELAY #2 3 LATCHED #3 4 PULSE SHAPING #4 5-6 For identification of the Siemens relay components, please refer to the figure on page 7.

EXAMPLE # 1, On Delay:

For ON Delay: With power to the relay off. Set the MODE SELECTOR SWITCH to A. This configures the relay as an ON Delay. Then select the desired TIME RANGE SELECTOR to the desired time range. Then select the proper PERCENT (%) of time range, on the PERCENT OF TIME RANGE DIAL. Turn power back on.
