5.4 Retransmission Group (G.RET)
Press SET/ENT key to select retransmission group. (Refer to parameter map.)
This parameter sets the type of retransmission mode to use. The setting options are PV,
SP, and LPS. See notes below for an explanation of the retransmission types.
The default setting is PV.
PV
These parameters are used to scale the retransmitting output. They set the high and low
limits for the retransmission output scale, as shown below. The retransmitting outputs will
transmit 4 mA at the low limit (RETL) and 20 mA at the high limit (RETH) values. These
limits are used when the retransmission type is set to PV or SP.
