How do I read the model code on my Manaras data plate?

The code is built in seven positions: model (e.g. OTBH), environment letter (W damp, C corrosive, X hazardous, none = standard), a 3-digit power code (voltage/phase/frequency), a horsepower digit, a mechanical digit (hoist side or chain type), a control letter (M/N/P) and any other modification. The decoder table on this page translates each position.

What does the W, C or X in a Manaras model code mean?

W is the Nema 4/12 damp/washdown trim, C is the Nema 4X corrosive-environment trim, and X is the CSA-certified hazardous location build. No letter means a standard Nema 1 unit.

What is the difference between an M, N and P control code?

M is the monitored ECB BOARD 070 supplied with photoelectric cells, N is the monitored board without the cells, and P is an external control panel. M and N operators supervise their entrapment protection per UL 325:2017.

Can you identify my operator from a photo of the data plate?

Yes, text or email a clear photo of the plate and we can identify the model, voltage, horsepower and control configuration before we arrive. Call (604) 206-5727.

How to Decode a Manaras Product Code

The full code on the data plate is built in seven positions. Worked example: OTBH W 611 3 1 M 00

Position	Meaning	Values
1. Model	Which operator	Any model code from the tables above (OTBH in the example)
2. Environment	Special environment trim, if any	(no letter) standard · W damp/washdown · C corrosive · X hazardous location
3. Power	Frequency, voltage & phase	611 120V 1-ph · 681 208V 1-ph · 621 240V 1-ph · 623 208V 3-ph · 673 240V 3-ph · 643 480V 3-ph · 653 600V 3-ph · 521 220V 1-ph 50Hz · 533 380V 3-ph 50Hz
4. Horsepower	Motor size	2 = 1/2 HP · 3 = 3/4 HP · 4 = 1 HP · 5 = 1-1/2 HP · 6 = 2 HP · 7 = 3 HP · 8 = 5 HP
5. Mechanical	Hoist mount / chain	Jackshaft hoist: 0 right, 1 left · Trolley chain: 0 #48(#410), 1 #41 · Sliding door chain: 1 #41 · Apartment chain: A
6. Control	Board configuration	M ECB monitored with photoelectric cells · N ECB monitored without photoelectric cells · P external control panel
7. Other	Additional modifications	Application-specific, if any

So the example decodes as: OTBH heavy-duty trolley with brake, washdown trim, 120V single-phase, 3/4 HP, #41 chain, monitored board with photo eyes. When you call us with the full code, we arrive with the right parts on the first visit.

The M/N/P letter matters more than it looks. An “M” or “N” operator runs the monitored BOARD 070 under ANSI/CAN/UL 325:2017, its entrapment protection devices are supervised, and a failed device stops the door closing on momentary contact. “M”-type operators are also the ones eligible for MIC smartphone control.
