An AI sales agent's damper actuator order, checked before it goes out

An AI sales agent prepares an order for modulating 24 V damper actuators from the public data sheets: which of the four sizes, how many, the damper area and shaft size, rotation, stroke time, enclosure rating, control signal and the control transformer. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of those data sheets and returns a verdict, every reason and the figures it computed.

Scope: Four modulating 24 V rotary damper actuators: LM24A-SR, NM24A-SR, SM24A-SR and GM24A-SR. See everything this validator covers

This validator models orders for the LM24A-SR, NM24A-SR, SM24A-SR and GM24A-SR modulating damper actuators as set out in their public data sheets, not just the scenarios shown below.

  • Damper size — the data sheets give air damper sizes up to approximately 1 square meter (LM24A-SR), 2 (NM24A-SR), 4 (SM24A-SR) and 8 (GM24A-SR); a larger damper is blocked.
  • Shaft — the universal shaft clamp takes 6 to 20 mm (LM24A-SR), 8 to 26.7 mm (NM24A-SR), 10 to 20 mm (SM24A-SR) and 12 to 26.7 mm (GM24A-SR); a damper shaft outside the range is blocked.
  • Rotation, speed, enclosure and signal — a maximum rotation of 95 degrees, a running time of 150 seconds for 90 degrees, protection class IP54 and a 2 to 10 V control signal; an application that needs more rotation, a faster stroke, IP65 or a 4 to 20 mA signal is blocked.
  • Supply — the wire-sizing power of each actuator (2, 4, 4 and 6.5 VA) times the number of dampers must fit the control transformer, and the total the agent states must match the computed total.

Any order for these four actuators that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Belimo does not publish list prices for these actuators, so this validator produces no price build-up or line-item quote), other Belimo actuators, valves, sensors and accessories, spring-return and on/off models, and installation. Assumptions: the transformer check compares the data sheet VA figure for wire sizing with the transformer rating, which is a conservative engineering check rather than a published Belimo rule; the data sheet sizes are approximate (“up to approx.”) and are treated as limits.

Where rules-based CPQ gets it wrong

Click to expand

Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

What the validator caughtTypical rules-based CPQPredictika
A damper area or shaft size that has to fit the chosen actuatorOnly with care
Each of the four sizes has its own area limit and shaft range, so the rules multiply by model and a rep can easily leave one inconsistent when changing the model.
The limits are derived from the chosen model and compared with the damper on every call.
A stated total VA that must match the computed total and fit the transformerOnly with workarounds
The total depends on the model and the number of dampers, and the stated figure is a free field that has to be compared with it.
The stated total is part of the request and is compared with the computed one on every call.
Application needs the actuator family cannot meet: stroke time, enclosure, 4 to 20 mAOnly with care
Each is a simple check, but they are easy to leave out of the order flow because they are not part of choosing the model.
They are in the same request and checked on every call, whatever the model.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.
All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

Narration transcript

The text of the narrated walkthrough, step by step.

  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for modulating 24 V damper actuators from the public data sheets: which of the four sizes, how many, the damper area and shaft size, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of those data sheets and returns a verdict, every reason and the figures it computed.
  2. I will start with the first request by the agent.
  3. The agent says. Please quote 8 LM24A-SR modulating damper actuators, one for each of 8 dampers. The dampers are 2.5 square meters with 16 mm shafts and need 90 degrees of rotation, and the application needs a full stroke in 150 seconds or less. The rest of the request is on screen. They will run on a 12 VA transformer and the quote states 16 VA in total.
  4. Before it goes out, the agent calls the validator.
  5. Blocked, with three findings, all in one answer. The damper area is 2.5 square meters, but the selected actuator is specified for dampers up to approximately 1 square meter. The controller outputs 4 to 20 mA, but these actuators take a 2 to 10 V control signal. The actuators need 16 VA for wire sizing in total, but the transformer is rated 12 VA.
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
  7. What this shows: for a damper area or shaft size that has to fit the chosen actuator, a rules-based CPQ is error-prone for this.
  8. Now the agent resubmits.
  9. The corrected request. It changes the actuator model to SM24A-SR, the transformer rating to 25 and the stated total to 32.
  10. It calls the validator again.
  11. Still blocked, with two findings, all in one answer. The controller outputs 4 to 20 mA, but these actuators take a 2 to 10 V control signal. The actuators need 32 VA for wire sizing in total, but the transformer is rated 25 VA.
  12. One finding cleared; still blocked on control signal not accepted and transformer too small.
  13. The agent resubmits once more.
  14. The revised request. It changes the controller output to 2 to 10 V and the transformer rating to 40.
  15. It calls the validator once more.
  16. This time the validator clears it.
  17. Both earlier findings are cleared, and the validator's figure matches the quote.
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
