Basler Electric BE1-25 - Manual (Page 17)

Push-to-Energize Output Pushbuttons
Two PUSH-TO-ENERGIZE OUTPUT switches are available to provide a means of verifying external
output wiring without the inconvenience of having to test the entire relay. These optional switches are
provided for each isolated output function (Sync-Check, Auxiliary Sync-Check and Voltage Monitor), and
may be actuated by inserting a thin, non-conducting rod through access holes in the front panel. See
Figure 2-1 for location.
MODEL AND STYLE NUMBER
The electrical characteristics and operational features of the BE1-25 Sync-Check Relays are defined by a
combination of letters and numbers that make up its Style Number. The model number, together with the
Style Number, describes the options included in a specific device, and appears on the front panel,
drawout cradle, and inside the case assembly.
Upon receipt of a relay, be sure to check the Style Number against the requisition and the packing list to
ensure that they agree.
Style Number Example
The Style Number identification chart (Figure 1-6) defines the electrical characteristics and operational
features included in BE1-25 relays. For example, if the Style Number were M9H-A6P-N4R0F, the device
would have the following:
BE1-25 Model Number (designates the relay as a Basler Electric, Class 100, Sync-Check Relay)
M Single-phase sensing
9 Expandable phase angle window
H Voltage Monitor relay and Push-to-Energize outputs
A6 0.1 to 99 seconds timing range
P Operating power derived from 125 Vdc or 120 Vac
N No target
4 Non-isolated contact sensing input
R Line and Bus Voltage Monitor; also a Voltage Difference Monitor with Condition Switches
internal to the relay.
0 No auxiliary output
F Semi-flush mounting
