R50

In Phase Monitor this feature restricts Live to Live Source Transfers to occur unless both Sources are within 7 electrical degrees or less of each other. (live Source to live Source transfers usually occur during transfer back to Source 1 or during Testing). R50 does not change the operation of the Automatic Transfer Switch in a power failure mode. After all timer functions have elapsed, the CHECKING FOR SOURCE SYNCHRO- NISM will be displayed as well as the direction of transfer (S1-S2 for example denotes transfer from Source 1 to Source2). When synchronism is accomplished, transfer will take place.

Notes: - If S2 Frequency is less than S1 Frequency, display will show a series of (- - - - -…..) symbols.

-If S2 Frequency is greater than S1 Frequency, display will show a series of (+++++…..) symbols.

-Each (-) or (+) symbol represents 10 electrical degrees out of phase. A maximum of 18 symbols (180 electrical degrees) can be monitored.

-The number of (-) or (+) symbols decrease as the two sources approach synchronism and increase as the two sources drift out of synchronism.

-If S1 and S2 Frequencies are identical, the

display will show a series of alternating symbols (++++- - - - …) which also indicate the

approximate out of phase degrees

In the event that the Sources do not come within 7 electrical degrees of each other within 60 seconds, the unit will display the message: SYNCH CHECKING and will allow the user to BYPASS. If the BYPASS button is pressed, the unit will display the message: WARNING MAY CAUSE DAMAGE TO THE LOAD. Pressing XFR will actually bypass the R50. Since R50 is a passive device, the length of time it takes to reach Synchronism is de- pendent on the frequency difference between the two Sources. Source 1 is usually a Utility and the frequency is not within the control of the consumer. Source 2 needs to be adjusted to create an adequate difference in order for the transfer to happen a timely fashion.

Note: For optimum performance, Source 2 Generator should be adjusted a Maximum of 2 Hertz above or below the Utility frequency, minimum of 0.1 Hertz. (58 to 59.9) or

(60.1 to 62) Hertz. Adjustment of Generator to 60Hertz could cause lengthy transfer delay.

R50 Feature can be turned ON or OFF via CFG Menu (see page 17). Factory Default if OFF.

S5P

Auto / Semi Manual selector

In "Auto" position, retransfer to Source 1 is automatic after the T timer has timed out. The T time delay is bypassed if Source 2 fails.

In "Manual", retransfer to Source 1 is upon depression of BYPASS DELAY button YEN or if Source 2 fails.

S12P

Auto / Manual Selector

In "Auto" position, the Automatic Transfer Switch functions automatically as specified with the Switch drawings.

In "Manual" the Automatic Transfer Switch will transfer to either direction upon depression of Source 1 or Source 2 transfer buttons.

Should Source 1 fail, the Generator (Source 2), will automatically start. Once transferred in Manual, the Switch maintains position selected even if selected power fails.

S13P

Transfer Commit. Configured via CFG menu. (see page 17) When this Feature is set to OFF:

The transfer Switch is not committed to transfer unless the outage duration is longer than the timers that precede the transfer to Source 2 position. This assumes that the outage will be an isolated event. When this Feature is set to ON: The transfer Switch is committed to transfer to Source 2 position once the W timer has begun timing, even if Source 1 power returns before the transfer to Source 2. This is to ensure that the transfer takes place, because one outage may be followed by another.

S14

Test / Auto / Source 1 Selector, Door mount

SW1

Auto/Off/Start Engine control selector, Door mount (Keyed or non-keyed operation available)

SW2

Auto / Off Engine control selector, Door mount (Keyed or non-keyed operation available)

SW3

Source Priority Selector Switch, Door mount

Allows selection of Source 1 or Source 2 to be the Prime Source. Transfer Switch will transfer to selected Prime Source if that Source is available. (Keyed or non-keyed operation available)

T

Time Delay (S1) Source 1 Stable Timer. To delay trans- fer to Source 1 (immediate retransfer on Source 2 fail- ure). Adjustable 0-60 minutes in 1 second increments.

Standard setting is 30 minutes. Adjust via SET menu (see page 18)

T3/W3

Elevator Pre-Signal Auxiliary Contacts: Open 0-60 seconds prior to transfer to either direction, re-closes after transfer.

U

(S2) Source 2 Stop Delay Timer. Allows Engine to run unloaded after switch retransfer to Source 1. Adjustable 0-60 minutes in 1 second increments. Standard setting is 5 minutes. Adjust via SET menu (see page 18)
