WELD SENTRY 2
SENTRY RELAY OUTPUTS
The Sentry is supplied with 2 DC solid state relays, K1 and K2, rated 3 to 60 volts, 1 amp (P/N 4-33049-
01). Two additional sockets, K3 and K4, are provided for user-supplied relays to be added. Either AC or
DC solid state relays can be used. AC solid state relays are rated 12 to 280 volts, 1 amp (P/N 555-086
).
Connections are made at the rear panel Relay Outputs connector (P/N 250-187) using the wiring harness (4-
31982-01) which is provided with the Sentry. The following table lists the specifications for wiring the
relay harness.
RELAY SIGNAL TIMING
The “Activation Delay” and signal duration for the Sentry's Output Relays can be programmed. The Relays
are not switched on until after the calculations for the measurement are completed
and
the specified
“Activation Delay” expires. The Activation Delay can be set from 0 to 500 milliseconds. The Relays will
“Remain On” until the next weld or for the specified time, from 0 to 500 milliseconds.
