Mode 7
The TOS (transmission output speed) monitor mode (mode 7) is a troubleshooting aid used to show the RPM of the transmission output shaft. This mode is useful when troubleshooting ESTC II system faults. In this mode, service personnel monitor the transmission output speed (TOS) while the machine is operated.The RPM of the transmission output shaft is shown on readout (13). Readout (13) shows in tens of RPM (X10). For example: 650 rpm is shown as "65" and 1520 rpm is shown as "152" on readout (13) .Note: The status indicators, as described in the Normal Mode section, also function in the TOS monitor mode.The display enters TOS monitor mode by pressing and holding both of the service switches at the same time until mode number "- 7 -." is shown on readout (13). Service mode indicator (8) is ON while the display is in TOS monitor mode. The display leaves TOS monitor mode by pressing and holding both of the service switches at the same time or when the key start switch is turned OFF. When in TOS monitor mode, the only function of the service switches is to change the display mode. For more information on changing modes, see the beginning of the topic Display Modes.
