(9905-292) for the Peak 150 control. The Peak 150 control is UL Listed for the US and Canada (cUL) for use in Class I, Division 2, Groups A, B, C, and D or non-hazardous locations only. -
Page 10: Chapter 2. Installation
* Modbus is a trademark of Modicon, Inc. Mounting The standard Peak 150 control enclosure must be vertically mounted on a wall or 19" (483 mm) rack, allowing sufficient room for lid opening and wiring access. Two welded flanges, one on the right side and one on the left side, permit secure mounting. - Page 11 Peak 150 Make sure that all inputs and outputs, including all shields, are NOT grounded outside the Peak 150 control box. Terminal block 1 (ground) is the only connection that should be wired to external ground. See Figure 2-2 for the control wiring diagram and terminal block numbers.

Page 15: Chapter 3. Control Description
Starting Modes The Peak 150 control has two starting modes: manual start mode and automatic start mode. Manual Start Mode With the manual start mode, speed control begins at minimum governor speed (as opposed to idle speed) (see Figure 3-1). -
Page 16: Operating Modes
Peak 150 Manual 85565 Operating Modes The Peak 150 control has three operating modes: manual mode, remote speed set mode, and combination mode. Manual Mode If the manual mode is configured, the turbine speed is adjusted solely by the front panel keys and the remote raise and lower discrete inputs. The remote speed setting analog input is ignored in this mode. -
Page 17: Chapter 4. Wiring
® All inputs and outputs to the Peak 150 control are made through terminal blocks inside the Peak 150 control enclosure. Wiring passes through two wiring ports on the bottom of the control. Inputs and outputs to the control are: •... - Page 18 Peak 150 Manual 85565 Version Input Voltage Frequency 1 (24 Vdc) 18–32 Vdc 2 (ac/dc) 90–150 Vdc 88–132 Vac 47–63 Hz No power switch is provided, the unit operates whenever power is applied. Input over-or under-voltage shutdown is not provided; if the +5 Vdc supply in the unit goes below 4.7 volts, the microprocessor will be reset.
- Page 19 Manual 85565 Peak 150 Discrete Inputs There are eight discrete inputs (shown in Figure 4-3), powered either by an internal 24 Vdc supply or by an external 5–28 Vdc supply: • Input #1 = Lower Speed • Input #2 = Raise Speed •...
