O O O O VERVIEW VERVIEW VERVIEW VERVIEW QualiTROL Electronic Temperature Monitor QualiTROL Electronic Temperature Monitor QualiTROL Electronic Temperature Monitor QualiTROL Electronic Temperature Monitor The 111-300 has a weatherproof enclosure, which can contain either one or two Model 111L/111W Electronic Temperature Monitor (ETM) units. The basic unit contains a Model 111W which can monitor winding current and then calculate the winding temperature.

E l e c t r o n i c T e m p e r a t u r e M o n i t o r • An RS485 2 wire or 4 wire port may be ordered as an option. This port uses Modbus RTU protocol to communicate the temperature data and the state of the unit to a remote communications device.
QualiTROL QualiTROL QualiTROL QualiTROL has been a leader in supplying pressure, liquid level, and temperature controls since 1945. An ISO 9001 system certified company; we are committed to providing you with quality and reliability, both in our products and in our service.
The 111L and 111W uses a 100 ohm Platinum RTD (Pt100) mounted in a universal sensor capable of mounting in any existing Qualitrol thermal well. A three wire RTD is recommended, a two wire RTD may be used if the lead length is short.
25 & TB1-26. There is no high voltage risk from an open circuit on the clip-on CT output wires. NOTE: The CT is ordered separately and must be supplied by Qualitrol. The clamp-on CT is a transducer, and not simply a CT; the 111W model will not accept a CT current input directly.
The optional enclosure heater kit (KIT-031-1), (sold separately), is intended for use with any 111-300 series unit. Two (2) adhesive backed kapton heaters @ 25 watts each, (supplied with the kit) are to be installed on the reverse side of the swing-out panel door approximately as shown in Figure 3a.

The ETM Configuration software is a Windows based program that allows the user to setup parameters in Qualitrol Model 111 and Model 118 series electronic temperature monitors via the RS232 port of the ETM. There is some variation in what parameters can be set in each model.
E l e c t r o n i c T e m p e r a t u r e M o n i t o r • Fan / Alarm / Trip setpoint and switching differential (hyteteresis) can be set to determine at what temperature the relays turn on and off.
E l e c t r o n i c T e m p e r a t u r e M o n i t o r known, then the values for each stage should be made the same. At no time should zeros be entered as values for these variables.
