acceptance; no operating temperature or heater qualification is represented.<\/figcaption><\/figure>\n<p>For an OEM panel, TX4-H wiring and setup should be treated as a controlled configuration task: identify the delivered suffix, map the terminals from the matching drawing, select the input and output functions, then record acceptance results before releasing the machine. Copying settings from a square controller or buying by \u201cPID, 48 mm wide\u201d is not sufficient.<\/p>\n<p>The sample used here is <strong>TX4-H W1T\/R-2<\/strong>, a tall panel-mounted controller. The matched TX4 manual identifies H as a 48 \u00d7 96 mm face with a 45 \u00d7 92 mm panel opening. These are revision-bound dimensions, not permission to machine a replacement panel without checking the delivered drawing.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Make_the_quotation_identify_the_configuration\"><\/span>Make the quotation identify the configuration<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Write the complete model on the purchase specification, together with supply voltage, sensor type, control-output interface and fitted alarm requirement. In the matched ordering table, W denotes relay\/SSR drive, 1 denotes Alarm 1, T\/R covers the listed thermocouple and RTD inputs, and supply code 2 denotes 100\u2013240 VAC\/DC. Confirm that the actual nameplate and the offered revision agree; a family feature list does not prove every option is installed.<\/p>\n<p>The photographed H unit shows Alarm 1 on terminals 17\/18. The manual also draws a family Alarm 2 circuit, but that is not evidence of a second fitted alarm on this W1 sample. A machine needing two independent alarm contacts must not be released on the assumption that a printed front indicator supplies the missing hardware.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Use_the_H_terminal_map_not_an_S_drawing\"><\/span>Use the H terminal map, not an S drawing<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table>\n<thead>\n<tr>\n<th>Interface<\/th>\n<th>Matched H manual<\/th>\n<th>OEM acceptance question<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Controller power<\/td>\n<td>1\/2<\/td>\n<td>Does the delivered supply code match the panel branch?<\/td>\n<\/tr>\n<tr>\n<td>Relay control output<\/td>\n<td>3\/4<\/td>\n<td>Does the load interface meet the applicable contact rating and duty?<\/td>\n<\/tr>\n<tr>\n<td>SSR drive<\/td>\n<td>5 positive \/ 6 negative<\/td>\n<td>Does the selected SSR input accept the documented drive?<\/td>\n<\/tr>\n<tr>\n<td>Thermocouple input<\/td>\n<td>13 positive \/ 14 negative<\/td>\n<td>Are input type, polarity and extension materials correct?<\/td>\n<\/tr>\n<tr>\n<td>RTD input<\/td>\n<td>13 B\u2032 \/ 14 B \/ 15 A<\/td>\n<td>Is the specified three-wire circuit correctly implemented?<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The manual lists a relay rating of 250 VAC, 3 A and SSR drive of 12 VDC \u00b12 V, no more than 20 mA. SSR drive is a control signal, not a heater-power output. Select the external switching and protective equipment from the real heater circuit; neither of these controller figures establishes the complete machine&#8217;s power capacity or safety function.<\/p>\n<figure data-image-role=\"product_detail\"><img decoding=\"async\" src=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/03-product-detail-79.png\" alt=\"TX4-H Wiring and Setup: An OEM Configuration and Acceptance Checklist  title=\" width=\"1536\" height=\"1024\" tx4-h wiring and setup: an oem configuration acceptance checklist title=\"\"><figcaption>Original product photographs retain their markings and casing.

Start with input type, temperature unit and resolution; then confirm the set-value limits, output selection and heating\/cooling mode. Changing input type, unit, decimal-point setting or set-value limits initializes the set value, so a changed parameter must trigger a fresh set-value check.<\/p>\n<p>Record whether the control output is RLY or SSR. The manual suggests control cycles of 20 seconds for relay output and 2 seconds for SSR output; those are starting recommendations, not universal process settings. Importantly, parameter reset does not initialize the output-selection parameter. A reset controller therefore still requires explicit output verification.<\/p>\n<figure data-image-role=\"application_b\"><img decoding=\"async\" src=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/02-application-b-80.png\" alt=\"TX4-H Wiring and Setup: An OEM Configuration and Acceptance Checklist  title=\" width=\"1536\" height=\"1024\" tx4-h wiring and setup: an oem configuration acceptance checklist title=\"\"><figcaption>A different adhesive-skid panel illustrates the configuration interface; commissioning and independent machine protection remain project requirements.<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Define_sample_acceptance_before_approving_a_lot\"><\/span>Define sample acceptance before approving a lot<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Use a configuration sheet covering the exact suffix, delivered drawing, sensor simulator or reference input, selected output, set value, alarm behavior and power-loss recovery. Record the expected and observed response for each test. Perform electrical work with the machine isolated and qualified personnel responsible for commissioning; unexpected heating must be prevented while configuration is incomplete.<\/p>\n<p>Separate controller acceptance from process acceptance. A correct display and output do not prove heater distribution, workpiece temperature or an independent overtemperature shutdown. The manual calls for fail-safe protection where controller failure could cause serious harm. Identify that protection in the machine design rather than naming the normal PID controller as the safety device.<\/p>\n<figure data-image-role=\"engineering_context\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.wehopower.com\/wp-content\/uploads\/2026\/10\/04-engineering-context-83.png\" alt=\"TX4-H Wiring and Setup: An OEM Configuration and Acceptance Checklist  title=\" width=\"1536\" height=\"1024\" tx4-h wiring and setup: an oem configuration acceptance checklist title=\"\"><figcaption>A source-grounded procurement checklist separates documented component facts from the completed equipment acceptance requirements.<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"What_an_OEM_should_send_with_an_enquiry\"><\/span>What an OEM should send with an enquiry<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Provide panel opening and available depth, input supply, sensor type and range, output interface, alarm count, heater-control architecture, target market, sample quantity and expected production demand.
