(000116) Owner's/Installation Manual for SMM 1 Introduction and Safety This page intentionally left blank. 2 Owner's/Installation Manual for SMM General Information and Setup Section 2: General Information and Setup Load Management Options Load management systems are designed to work together to avoid a generator from being overloaded by large appliance loads. Options include: · Smart Management Modules (SMMs) · Smart A/C Module (SACM)--standard in single- phase 100800 amp RTS or RXS transfer switches. These options can be used in conjunction or separately. Application Considerations Generator overload condition is determined by generator frequency. Loads are shed when frequency drops below a preset value for a predetermined time. A SMM can be used individually or in conjunction with a SACM to manage a combined total of eight loads. · SACM inputs 14 have fixed priorities of 14, respectively. SMM's can be individually set to priorities 18. · To reduce loads returned to the generator all at once, it is best to set SMM priorities to follow after the last HVAC load has returned. This allows the generator to accept loads gradually, reducing the potential for additional nuisance load shed events. · A SMM can share a priority with an A/C priority on the SACM provided the generator is sized to handle the combined surge load from both appliances. · Sharing priorities can allow up to 12 loads to be managed in a correctly sized system. In any combination of modules, recovery times after a loss of utility power or shutdown due to overload are shown in Table 2-1. NOTE: For digital thermostats where a 24 VAC thermostat wire is not available, a SMM must be used to break the power at the HVAC load itself. Smart Management Module (SMM) Any 240V loads up to 100A (resistive, 90A inductive), including central air conditioners, can be managed using a SMM. The system can accommodate up to eight individual SMMs. NOTE: SMMs are self-contained and have individual built-in controllers. Table 2-1. Priority Settings Priority 1 2 3 4 5 6 7 8 Recovery Time 5 minutes 5 minutes 15 seconds 5 minutes 30 seconds 5 minutes 45 seconds 6 minutes 6 minutes 15 seconds 6 minutes 30 seconds 6 minutes 45 seconds SACM Yes Yes Yes Yes NA NA NA NA SMM Yes Yes Yes Yes Yes Yes Yes Yes Owner's/Installation Manual for SMM 3 General Information and Setup SMM and Carton Contents Priority Dial (A)--Sets module priority. NOTE: PRIORITY MUST BE DIFFERENT for each module in an installation. Priority sets the order in which loads recover from a load shed event. Recovery time from a load shed event is five minutes for Priority 1. Each priority after Priority 1 waits an additional 15 seconds after the initial recovery time. See Table 2-1. Lockout Switch (B)--Enables or disables lockout function. Switch positions are LOCKOUT LOAD ON GENERATOR (enabled) and LOCKOUT DISABLED. See Table 2-2. NOTE: Recovery time is based on priority dial settings. See Table 2-1. Test Button (C)--Disables contactor output for a specified time. LED (D)--Provides module status. See Table 2-3. Contactor (E)--Normally OPEN. If generator begins to overload, the contactor opens to take load off generator power. See Connections. Mounting Holes (F)--Internal enclosure mounting holes provide clean and sturdy mounting. Directional Arrows (G)--Provided for mounting purposes. Priority Decal (H)--Provided for recording priority of each module in installation. Install on electrical panel. AB CD H F F E 009380 G Figure 2-1. SMM Features and Controls 4 Owner's/Installation Manual for SMM General Information and Setup Setting Lockout SMMs are equipped with a lockout provision. The SMM can be set to enable lockout mode if load is identified as non-essential and does NOT need to operate on backup power during generator overload. Load can be an entire subpanel of multiple branch circuits. Proceed as follows to set SMM to enable standard lockout mode: 1. See Figure 2-2. Slide lockout switch (1) to LOCKOUT LOAD ON GENERATOR. 2. Set mode selector jumper (4) on the control board as directed in Jumper Locations. Jumper Locations See Figure 2-2. The SMM control board is equipped with two movable jumpers (2). Jumper locations are indicated on the diagram: · (3) Frequency Jumper · (4) Mode Selector Jumper (identified on control board as "Lock Out Jumper") The frequency jumper is factory set at the 60 Hz position. The mode selector jumper is factory set at position "A", which is considered standard for most installations. Jumpers should remain in place except when operating the unit under either or both of the following conditions: · Operating the unit at 50 Hz requires moving frequency jumper to "50 Hz" position. · For installations in areas with unstable utility power, set mode selector jumper to position "B". To move a jumper: 1. Remove power. 2. Grasp jumper and pull straight up until it clears the pins. 3. Move jumper to new location and press it gently onto the pins until seated. NOTE: To avoid bending or breaking pins, do not rock jumper, use excessive force, or pull sideways to remove it from the SMM control board. 1 2 3 Figure 2-2.

LED States Mode Generator Generator Generator Utility Generator or Utility Generator or Utility Note Module detected an overload and shed its load. This state only occurs in generator mode, or during a first time utility power-up for five minutes of initial operation. Module detected an overload while trying to recover from a shed situation. Operation is disabled for 30 minutes. This state only occurs in generator mode. Module output is disabled and there is no power to the appliance while in generator mode and generator is overloaded. Lockout switch must be ON. See Table 2-2. Lockout switch operates in generator mode only. It has no function in utility mode. LED is solid, indicating load is connected. Lockout switch must be ON. See Table 2-2. Indicates appliance has power. This is the default in utility mode. It is the normal operating state in generator mode when an overload is not detected. Test button triggers a typical shed condition and overrides all other states except generator lockout switch ACTIVE state. NOTE: Actual test time varies depending on SMM priority setting. Use the following formula to calculate test time: Time = (P-1) x 15 seconds, where P represents priority setting. Example: SMM Priority 6 test time = (6-1) x 15 seconds, or 75 seconds. 6 Owner's/Installation Manual for SMM Owner's/Installation Manual for SMM Start Load is OFF NO Have five minutes elapsed?

Verify LED begins to flash at one second intervals. 3. All contactors will close after five minutes. LED will illuminate and remain ON. NOTE: The five-minute delay allows magnetism to dissipate from the air conditioner compressor. This promotes easier starting and eliminates the potential for reverse compressor operation. Installation Summary · Install cover on electrical panel. · Install covers on modules. Setting Priorities High priority 240 VAC loads should be set to the highest priorities so those loads recover first in the event of generator overload. NOTE: The highest priority, and first load to activate, is Priority 1. The last load to activate is Priority 8. Setting priority determines timing for three scenarios: · Order in which loads recover · Delay time until power returns during an outage · Delay time for post load shed recovery An example configuration is shown below. Configurations will vary depending on customer prioritization of loads: Priority 1: Baseboard heat Priority 2: Air conditioner Priority 3: Range Priority 4: Clothes Dryer Priority 5: Non-essential circuits Priority 6: Pool pump or hot tub Priority 7: Other circuits Priority 8: Other circuits 1. Set the priority of each SMM as desired (using the example configuration for reference). 2. Apply priority decal in a suitable location on electrical panel to record chosen priority designations. 3. Record priorities on decal. Owner's/Installation Manual for SMM 11 Installation, Tests, and Troubleshooting Troubleshooting See Table 3-2 for troubleshooting problems, causes, and corrections.
