RT-SVX34C-EN 11 7
Sequence of Operation
Low Pressure Control (LPC) Sequence of Operation (ReliaTel Control)
When the LPC is opened for one (1) continuous second, the compressor for that circuit is turned
off immediately. The compressor will not be allowed to restart for a minimum of three (3) minutes.
If four consecutive open conditions occur during the first three minutes of operation, the
compressor will be locked out, a diagnostic communicated to ICSTM if applicable, and a manual
reset will be required to restart the compressor.
High Pressure Control and Temperature Discharge Limit
(ReliaTel Control)
The Temperature Discharge Limit (TDL) is located in the Compressor Output circuit and is
connected in series with the High Pressure Control (HPC). The RTRM will register an auto reset
lockout if either the high pressure control switch or the temperature discharge limit opens during
compressor operation. If the compressor output circuit is opened four consecutive times during
compressor operation, the RTRM will generate a manual reset lockout.
