Older Ambex YM-2 with Watlow Controller
Bridge5479	#1 Posted on 05/21/2020 6:05 PM
Newbie Posts: 1 Joined: May 20, 2020	Recently purchased an older manually operating Ambex YM-2 Roaster (Propane). Plate is missing for production year, but informed it likely is a 1997 model. The Watlow powers on, but appears to not be fully wired. Definitely the probe wires are not connected, if not in addition others. The Watlow model is 935A-1CD0 In addition the red covered switch has no effect on any of the operation. The question(s), would anyone have a schematic or photo of wiring to the Watlow? Another question, is there an upgraded Watlow or other controller that would be more effective for this roaster to connect with a Mac/Ipad operating system for profiles? Thank you. #Bridge5479 Bridge5479 attached the following images:

You can find the user manual which has wiring information at their site: https://www.watlow.com/resources-and-...er-Manuals Search for 935A in the keyword search box and a PDF should be available. ---Jack KKTO Roaster.
