g. Accessory outlet. The accessory outlet operates in conjunction with a
timer circuit. The outlet can be used to plug in a recommended safelight, or a
statice liminator over the processor.
Also located on the front of the
processor are the flow meters, developer temperature thermometer, water inlet,
silver recovery connector, drain outlets, replenisher inlets and the air
h. Dryer lamp switch. The dryer lamp switch (fig 2-9) controls the flood
lamp, which provides illumination for the dryer cabinet.
i. Dryer thermostat.
The thermostat controls the minimum required
temperature in the dryer cabinet.
There is also a safety device (backup
thermostat) that rings a bell and turns off the dryer heaters if the
temperature exceeds 160F.
The normal range of temperature selection by the
thermostat is up to 155F. When the heaters are ON, a pilot lamp illuminates.
j. Dryer thermometer.
The thermometer indicates the temperature of the
air in the dryer cabinet, in centigrade, fahrenheit, or both.
k. Damper controls. The damper controls can be positioned from 0 through
8 to control the amount of air admitted to the air tubes. Position 0 is fully
closed, and position 8 is fully open.
2. The only other control you need to adjust is the developer temperature
control, located under the plumbing splash guard. The control knob sets the
thermostat to the desired developer temperature.

DESCRIBE THE PREOPERATIONAL INSPECTION, DAILY STARTUP, AND SHUTDOWN PROCEDURE
1. Operation. Begin the operation of the processor by checking the squareness
of the feed tray. You place a sheet of 8 by 10 inch film on the tray and then
push it forward until it is in contact and square with the feed and detector
rollers. To square the tray, loosen two wing nuts under the tray and move the
tray as necessary.
a. The Versamat has detector rollers that sound a buzzer if two
thicknesses of film or a damaged film is fed into the processor. If the buzzer
sounds during an operation, pull the film from the rollers to prevent a
possible failure later in the processing cycle.
b. The bottom detector roller, shown in Figure 2-10, activates micro-
switches to activate the double thickness alarm (one switch on each end of the
roller) and the replenisher system (center switch). As the film passes between
the rollers, the center switch closes, turning on the replenisher pumps. When
the film exits the rollers, a bell signals that the next film may be fed into
the processor. If two thicknesses of film enter the feed rollers, a switch on
the end of the roller closes, turning on the warning buzzer.
During MANUAL
operation of the replenisher system, the center switch is removed from the
circuit and the pumps run continuously.
