3 Operating the SAMMS-MV Device

3.4 Output Devices

You can use the following SAMMS-MV output devices:

AC Outputs

The SAMMS-MVX device provides up to three AC coil drivers

capable of driving contactors up to size H6, while SAMMS-MVE

provides one coil driver.

Control Relays

The device provides up to eight software-controlled relays.

These relays are helpful in local two-wire and other applications

requiring maintained contacts.

Timing Relays

The SAMMS-MV device contains four internal software timing

relays. You can configure all four timers as on-delay timers;

however, if needed, you can configure the two adjustable timers

(timing relays TR1 and TR2) as either on-delay or off-delay

timers. Using the Hand Held Communicator, you can program

timing relays TR1 and TR2 from 0 through 200 seconds

(functions F13 and F14). Timing relay TR3 has a fixed 1 second

delay, and timing relay TR4 has a fixed 30 seconds delay. Table

3.1 illustrates the type of timers used on the device and their

ranges.

Pilot LEDs

The SAMMS-MVX device contains three light bars on the front

panel, while the SAMMS-MVE contains two light bars. Light bar

L1 is reserved and must be used as the STOP or OFF LED. You

can configure L2 and L3 at your discretion. The Hand, Off and

Auto LEDs correspond to the Hand, Off and Auto pushbuttons

on the front panel as illustrated in Figure 3.4. You can use the

Incomplete Sequence LED in reduced-voltage applications or

to verify contactor operation. Refer to Figure 3.4 for the location

of the LEDs and Table 3.2 for a description of the LED states.

Flashing Pilot LEDs

The front panel contains two or three flashing light bars that

indicate various conditions such as on-delay timing. These

flashing light bars, L1, L2 and L3 as defined above, indicate

different output devices if they are flashing rather than if they are

on constantly. Refer to Figure 3.4 for an illustration of pilot LEDs.

3.5 Input Devices

You can use the following input devices with the SAMMS-MV

device.

Remote AC Inputs

For SAMMS-MVX you can use four 120 VAC or VDC inputs for

remote control, or you can use one input for SAMMS-MVE.

Front Panel Pushbuttons

The SAMMS-MV device has six front-panel pushbuttons for

local control of the device. You must use pushbutton 1 (PB1) for

stopping the motor. You must use three of the pushbuttons

(PB4-PB6) for the Hand, Off and Auto functions if these

functions are used in your configuration. If these functions are

not used, you may use PB4-PB6 for other functions. You can

configure the other two pushbuttons (PB2 and PB3) at your

discretion. Refer to Figure 3.4 for assignment of pushbuttons.

Insert labels are used to identify the function associated with

each pushbutton or light bar.

Software Auxiliary Contacts

Any number of internal (software) auxiliary contacts can be

configured. These contacts show either a normally open (NO)

or normally closed (NC) status. You can set up these auxiliary

contacts using the SAMMS-MV software. Through the

SAMMS-MV software, the pilot LEDs also have auxiliary con-

tacts.

Software Timer Inputs

Each timer has an unlimited number of normally open (NO) and

normally closed (NC) contacts. Timers configured as on-delay

timers have an unlimited supply of normally open timed-closed

(NOTC), and normally closed timed-open (NCTO) contacts.

Timers configured as off-delay timers have an unlimited supply

of normally open timed-open (NOTO), and normally closed

timed-closed (NCTC) contacts.

Communications Inputs

A serial, RS-485 communications port is located on the back of

the device for external communications.
